搬家原因英文作文Title: Reasons for Relocating。
Moving to a new residence is a significant decisionthat individuals or families often make for various reasons. In this essay, we will explore some common motivations behind relocating to a new place.First and foremost, one of the primary reasons for moving is job-related. Career opportunities play a pivotal role in determining where individuals choose to reside. People may relocate to pursue better job prospects, higher salaries, or career advancement opportunities. Whether it's securing a new job in a different city or transferring to another branch of the same company, career considerations often drive relocation decisions.Secondly, education can be a compelling factor in moving to a new location. Families with children may choose to relocate to areas with renowned schools or educationalinstitutions that offer superior academic programs or extracurricular activities. Access to quality education is a priority for many parents, and they are willing to move to ensure their children receive the best possible learning opportunities.Moreover, lifestyle preferences and amenities also influence the decision to move. Some individuals may seek a change in scenery, preferring to reside in urban areas bustling with cultural activities, restaurants, and entertainment options. Others may prioritize a quieter, suburban lifestyle with access to parks, recreational facilities, and a sense of community. The desire for a specific lifestyle often prompts people to relocate to areas that better align with their preferences and values.Additionally, family considerations can prompt individuals to move closer to loved ones or support networks. Whether it's to be nearer to aging parents, siblings, or extended family members, the need for familial support and connection can drive relocation decisions. Being in proximity to family can provide emotional support,childcare assistance, and a sense of belonging, especially during significant life events or emergencies.Furthermore, economic factors such as the cost ofliving and housing affordability can influence relocation choices. Rising housing costs, property taxes, or expenses associated with daily living can compel individuals or families to seek more affordable alternatives elsewhere. Moving to a region with a lower cost of living canalleviate financial stress and improve overall quality of life.Moreover, environmental considerations, such as climate preferences or natural disaster risks, can prompt relocation. Some individuals may seek milder climates or escape harsh weather conditions, while others mayprioritize living in areas less prone to hurricanes, earthquakes, or wildfires. Concerns about environmental sustainability and access to clean air and water may also influence decisions to move to greener or more eco-friendly locations.Lastly, personal growth and self-discovery can be driving forces behind relocation. Moving to a new place offers opportunities for adventure, exploration, and personal reinvention. It allows individuals to step out of their comfort zones, meet new people, and experience different cultures, ultimately leading to personal and professional growth.In conclusion, there are various reasons whyindividuals or families choose to relocate to a new place. Whether it's for career advancement, education, lifestyle preferences, family considerations, economic factors, environmental concerns, or personal growth, the decision to move is often a deeply personal one driven by a combination of motivations. Each relocation represents a new chapter in life, filled with opportunities for fresh beginnings and exciting experiences.。

After watching a science popularization video on earthquake resistance, I have gained a deeper understanding of the importance of earthquake preparedness and the knowledge of how to respond to earthquakes.Firstly, the video emphasized the significance of earthquake resistance. Earthquakes are unpredictable, and when they occur, they can cause severe damage to buildings, roads, and other infrastructure. Therefore, it is crucial to strengthen earthquake resistance to minimize the losses caused by earthquakes.Secondly, the video provided knowledge on how to respond to earthquakes. When an earthquake strikes, one should remain calm and quickly find a safe place to take shelter, such as under a sturdy desk or against a wall. It is important to avoid staying near windows, glass doors, or other fragile objects that could shatter during the quake. Additionally, the video mentioned the importance of earthquake drills. Regular drills can help people become familiar with the correct actions to take during an earthquake, thereby increasing their chances of survival.In conclusion, the science popularization video on earthquake resistance has made me realize the importance of earthquake preparedness and the knowledge of how to respond to earthquakes. In the future, I will pay more attention to earthquake resistance and actively participate in earthquake drills to enhance my ability to respond to earthquakes.。
非线性动态方法评估重合钢筋建筑的地震抗性说明书
7th International Conference on Mechatronics, Control and Materials (ICMCM 2016)Assessment of seismic resistance of the reinforced concrete buildingby nonlinear dynamic methodOleg Vartanovich Mkrtychev1, Marina Sergeevna Busalova2*1Head of the Research laboratory “Safety and Seismic Resistance of Structures” Professor of theDepartment “Strength of Materials”Moscow State University of Civil Engineering (National Research University) 26, YaroslavskoeShosse, Moscow, Russia2Engineer of the Research laboratory “Safety and Seismic Resistance of Structures” Moscow State University of Civil Engineering (National Research University) 26, Yaroslavskoe Shosse, Moscow,Russia**************************Keywords:direct dynamic method, non-linearity, seismic impact, reinforced concrete structures, near-collapse criterion.Abstract.The article studies the reaction of the 5-storey reinforced concrete building of the cross-sectional wall structural scheme to the seismic impact. Bearing structures of the building were simulated by the three-dimensional finite elements, connecting concrete and reinforcement, in the software application LS-DYNA. The calculation was carried out by the direct dynamic method using the directly integrated equation of motion according to the explicit scheme. Using this method for calculation allows to make calculations in the temporary area and also to take into account the nonlinearities in the analytic model. In particular, the physical non-linearity is taken into account by means of the non-linear diagram of the concrete deformation. To create an adequate analytic-dynamic model the authors of the article developed the method allowing to take into account the actual reinforcement of the structure. The research conducted allows to estimate the reaction of the 5-storey reinforced concrete building to the set seismic impact.IntroductionThe base of the edition of SP 14.13330.2014 SNiP II-7-81* “Construction in Seismic Regions” [1] acting since 2015 takes the requirements of the two-level calculation of the seismic impact. The earthquake analysis corresponding to the level of the maximal design earthquake shall be performed according to the near-collapse criterion. It means that the calculation methods shall directly take into account the non-linear character of the structural deformation (physical, geometrical, structural non-linearities). However, now in Russia the corresponding method and verified dynamic model allowing to make calculations at the level of maximal design earthquake are not available. The authors of the article developed the method allowing to take into account the non-linear properties of concrete when making calculations of seismic impact, and also to include the elements of the connection of concrete and reinforcement into the analytical model taking into account the actual reinforcement of the structure.Setting of problemConcrete is a complicated composite material that consists mostly of the filling and the grouting, and at the different impacts its reaction can vary from brittle fracture at tensioning to yield behavior at compression. Non-linear diagram of concrete deformation taking into account the physical non-linearity is shown in the Figure 1 [2].Figure 1. Non-linear diagram of concrete deformationTo solve the problem it is necessary to have a corresponding material model. The Figure 2 shows the most complete models describing adequately the work of concrete at deformation (CSCM – Continuous Surface Cap Model) [3].Figure 2. Mathematical model of concrete (CSCM – Continuous Surface Cap Model) Concrete yield surface is described by the invariants of the stress tensor that in turn are determined from the formula (1)-(3).13J P=(1)212ij ijJ S S′=(2)313ij jk kiJ S S S′=(3)where1J is the first invariant of the stress tensor, 2J′ is the second invariant of the stress tensor, 3J′is the third invariant of the stress tensor,ijS is stress tensor, P is pressure.To study the actual reaction of the structure to the seismic impact it will not be sufficient to take into account the nonlinear properties of the concrete only. To show the real picture of thedeformation it is necessary to include the actual reinforcement into the analytic dynamic model, that is, to simulate the reinforcement cage of the building under analysis in the structural design [4].The Figure 3 shows the structural design of the five-storey reinforced concrete building of the cross-sectional wall structural scheme. All bearing structures are simulated by the three dimensional elements for concrete and bar elements for reinforcement [5].Figure 3. Structural design The Figure 4 shows the reinforcement cages of the building.Figure 4. Reinforcement cageCalculation resultsCalculation was made by the software application LS-DYNA by the direct dynamic method [6]. Equations of motion (4) were integrated directly according to the explicit scheme (5):a ++=Mu Cu Ku f (4)where u is nodal displacement vector, =uv is nodal velocity vector, =u a is nodal acceleration vector, M is mass matrix, C is damping matrix, K is rigidity matrix, af is vector of applied loads. /22t t t t t t t t t t +∆+∆+∆∆+∆=+u u v (5)This method allows to take into account the geometrical, physical and structural nonlinearities andalso to make calculations in the temporary area (dynamics in time).Three-component diagram was used as a design seismic impact corresponding to the intensity 9 earthquake (Figure 5). a)b)c)Figure 5. Three-component accelerograma)component X, b) component Y, c) component ZIsofields of the plastic deformations after the earthquake (t = 30 s) are shown in the Figure 6. Figure 6. Isofields of the plastic deformations after the earthquake at the moment of time t = 30 s The character of the plastic deformations corresponds completely to the character of cracks distribution. The Figure 6 shows that the bearing structures of the building of this structural scheme were damaged seriously but the building did not collapse, that means the conditions of the special limit state (near-collapse criterion) are satisfied. As a result of the conducted research, the seismic resistance of the building according to the near-collapse criterion was determined as intensity 9.ConclusionsThe analysis of the data obtained as a result of the research allows to conclude that for the adequate estimation of the reaction of the structure to the seismic impact it is necessary to make calculations in the nonlinear dynamic arrangement taking into account the nonlinear diagrams of concrete deformation and also to add the actual reinforcement into the structural design. The use of the offered method of the buildings earthquake calculations at the design stage will allow to estimate adequately the level of seismic resistance of the building structures.AcknowledgementsThis study was performed with the support of RF Ministry of Education and Science, grant No.7.2122.2014/K.References[1].SP 14.13330.2014 SNIP II-7-81.

Earthquakes are one of the most powerful and destructive natural disasters that can occur anywhere in the world.They are the result of sudden movements in the Earths crust, which can cause the ground to shake violently and sometimes lead to catastrophic consequences.In this essay,I will discuss the causes of earthquakes,their effects on human society,and the measures that can be taken to mitigate their impact.Causes of EarthquakesThe Earths crust is divided into several tectonic plates that are constantly moving due to the heat from the Earths mantle.These movements can cause the plates to collide,pull apart,or slide past each other.When the stress between the plates becomes too great,the energy is released in the form of seismic waves,resulting in an earthquake.This process is known as plate tectonics.There are three main types of plate boundaries where earthquakes can occur:1.Convergent Boundaries:These occur when two plates move towards each other,often resulting in the formation of mountain ranges or deep ocean trenches.2.Divergent Boundaries:Here,plates move away from each other,allowing new crust to form as magma rises from the mantle.3.Transform Boundaries:Plates slide past each other horizontally,often creating fault lines that can be the source of earthquakes.Effects on Human SocietyThe effects of earthquakes can be devastating.They can cause buildings to collapse, roads to be destroyed,and essential services such as water and electricity to be disrupted. In addition to the immediate physical damage,earthquakes can also lead to secondary disasters,such as tsunamis,landslides,and fires.The impact of an earthquake is not limited to the physical environment.It can also have profound social and economic effects.For example,the loss of homes and businesses can lead to displacement and economic hardship.The psychological impact of experiencing an earthquake can also be significant,leading to increased levels of stress and anxiety. Mitigation MeasuresTo reduce the impact of earthquakes,several measures can be taken:1.Building Codes:Strict building codes can ensure that structures are designed towithstand the forces generated during an earthquake.2.Early Warning Systems:These systems can provide valuable seconds or minutes of warning before the ground starts to shake,allowing people to take cover and minimize damage.cation and Awareness:Educating the public about earthquake safety and preparedness can help reduce panic and improve the overall response to an earthquake.4.Infrastructure Planning:Careful planning can help ensure that critical infrastructure, such as hospitals and emergency services,are located away from highrisk areas and are built to withstand earthquakes.5.Research and Monitoring:Ongoing research into the causes and patterns of earthquakes can help scientists better predict and prepare for future events.In conclusion,while earthquakes are a natural phenomenon that cannot be prevented, their impact on human society can be significantly reduced through careful planning, education,and the implementation of effective mitigation measures.By understanding the causes of earthquakes and taking proactive steps to prepare for them,we can help protect our communities and minimize the damage caused by these powerful events.。

地震自救自护知识英语作文
Earthquakes are one of the most powerful and terrifying natural disasters that can strike without warning, causing widespread destruction and loss of life. As a high school student who has been educated on the importance of disaster preparedness, I feel it is crucial to share some knowledge about selfrescue and protection during an earthquake.Growing up, I was always fascinated by the stories of survival and the resilience shown by people who have experienced such calamities. One of the most important lessons Ive learned is that being prepared can make a significant difference in the outcome of an earthquake. This preparation involves not only understanding the science behind earthquakes but also knowing practical steps to take when one occurs.Firstly, it is essential to have a basic understanding of what happens during an earthquake. Earthquakes occur when there is a sudden release of energy in the Earths crust that creates seismic waves. These waves can cause the ground to shake violently, leading to the collapse of buildings and other structures. Knowing this, it is clear that the first step in selfrescue is to find immediate shelter.When the ground starts to shake, its critical to Drop, Cover, and Hold On. This means getting down on your hands and knees to avoid being knocked over, taking cover under a sturdy piece of furniture like a table or desk, and holding on to it to protect yourself from falling debris. This simple yet effective method can significantly reduce the risk of injury.Another important aspect of selfprotection during an earthquake is to beaware of your surroundings. If you are indoors, stay there, away from windows and other glass objects that could shatter. If you are outdoors, move to an open area away from buildings, trees, streetlights, and utility wires. Being conscious of your environment can help you avoid potential hazards.Once the shaking stops, its essential to assess the situation and take the necessary steps for your safety. Check for injuries and provide first aid if needed. If you are trapped under debris, try to signal for help by tapping on a pipe or wall. Its also important to be prepared for aftershocks, which can occur minutes, hours, or even days after the initial quake.In addition to knowing what to do during an earthquake, its equally important to be prepared before one happens. This includes creating an emergency plan with your family, assembling a disaster kit with essential supplies like water, food, a flashlight, and a first aid kit, and securing your home by bolting down furniture and appliances.One of the most inspiring stories Ive come across is that of a community in Japan, known for its high earthquake risk. They have not only implemented strict building codes but also integrated disaster education into their school curriculums. This proactive approach has significantly reduced the impact of earthquakes on their communities.In conclusion, knowledge is power, especially when it comes to surviving an earthquake. By understanding the science behind these natural disasters, knowing the right actions to take during an earthquake, andbeing prepared with an emergency plan and supplies, we can increase our chances of staying safe and protecting our loved ones. Its a responsibility we all share, and one that can make a lifesaving difference in the face of such a powerful force of nature.。
