某多层食堂结构设计

摘要

本工程为长春市多层食堂工程,采用框架结构,主体为二层,无地下室。建筑面积约为2500平米,本地区抗震设防烈度为7度,近震,场地类别为II类场地。主导风向为西南,基本风压0.65KN/M,基本雪压0.35 KN/M。楼?屋盖均采用现浇钢筋混凝土结构。

本设计贯彻“实用、安全、经济、美观”的设计原则。按照建筑设计规范,认真考虑影响设计的各项因素。根据结构与建筑的总体与细部的关系。

本设计主要进行了结构方案中横向框架第3轴抗震设计。在确定框架布局之后,先进行了层间荷载代表值的计算,接着利用顶点位移法求出自震周期,进而按底部剪力法计算水平地震荷载作用下大小,进而求出在水平荷载作用下的结构内力(弯矩、剪力、轴力)。接着计算竖向荷载(恒载及活荷载)作用下的结构内力。是找出最不利的一组或几组内力组合。选取最安全的结果计算配筋并绘图。此外还进行了结构方案中的室内楼梯的设计。完成了平台板,梯段板,平台梁等构件的内力和配筋计算及施工图绘制。对楼板进行了配筋计算,本设计采用桩基础,对基础承台和桩进行了受力和配筋计算。

整个结构在设计过程中,严格遵循相关的专业规范的要求,参

考相关资料和有关最新的国家标准规范,对设计的各个环节进行综合全面的科学性考虑。总之,适用、安全、经济、使用方便是本设计的原则。设计合理可行的建筑结构方案是现场施工的重要依据。

Multi-layer mall structure design

Pick to

This project for changchun multi-layer mall project, adopt frame structure, main body for four layers, without the basement. This region seismic fortification intensity of 7 degrees, the recent earthquake, site categories for class II field. Leading the wind to the southwest, basic wind pressure for 0.65 KN/M, basic snow KN/M 30k pressure. Floor, roof adopts cast-in-situ reinforced concrete structure This design implementation "the practical, safe, economic, beautiful" design principle. According to the architectural design standard, carefully consider the various factors influence the design. According to the overall structure and building the relationship with details This design main structure plan in the first three axis horizontal frame aseismic design. In determining the framework, after the first layout between layers of load calculation, then represent value for using vertex displacement method, and then from the earthquake cycle

by bottom shear method to calculate the size of horizontal seismic load, and then find out under horizontal loads of structural internal force moment, shear force and axial force. Then calculating vertical load constant load and live load under the action of structural internal force. The most unfavorable is to find a group of or several groups of internal force combination. Select the security reinforcement and the results calculated animation In addition to the structure scheme design of indoor stair. Completed the flat bedplate, ladder section board, platform beam of internal force and the component such as reinforcement calculation and construction drawing. The reinforcement of floor, this design USES the calculation of pile foundation, pile caps and based on the mechanical and reinforcement calculation The whole structure in the design process, strictly abide by relevant professional the requirement of the specifications, reference related material and the relevant and up-to-date, national standards for design of each tache of comprehensive scientific consideration. Anyhow, applicable, safety, economy, use convenient is this design principles. Design of structure is rational and feasible scheme is the important basis of construction siteKeywords: frame structure, seismic design,
