摘要

该工程位于XXXX，地震设防烈度为8度。本工程采纳框架结构。该楼为四层，层高米，总高米，总建筑面积为4019平方米。

总的设计思路：在建筑结构的两个主轴方向别离考虑水平地震作用，各方向的水平地震作用应全数由该方向抗侧力结构承担。采纳框架结构计算的近似法求解内力，即：求竖向荷载作用下的内力按无侧移框架用弯距二次分派法，求水平地震作用下的内力按三角形散布用D值法。最后利用钢筋混凝土的相关原理进行构件配筋计算及校核。

具体设计步骤分十步：

第一步：荷载统计，包括各层恒载、活载，计算各楼层重力荷载代表值。

第二步：刚度计算，包括各梁、柱的线刚度，柱的抗侧刚度D，按框架分析的D值法计算。

第三步：框架自震周期的计算。

第四步：验算侧移，包括顶部位移和层间位移。

第五步：内力计算，用反弯点法求得各柱端弯矩、梁端弯矩和梁端剪力。

第六步：竖向力作用下框架内力计算。采纳弯矩二次分派法，对梁端弯矩调幅。

第七步：综合配筋计算。将水平地震力与竖向力作用下别离求出的内力进行不利组合，再依照取得的几组不利组合别离进行框架梁、柱的配筋计算，取其中的最大值来配筋。

第八步：利用CAD软件绘制一榀框架配筋图、楼板配筋图和梁柱截面配筋图。

第九步：楼梯设计，依照建筑设计中确信的楼梯参数，对楼梯的梯段板、平台板和平台梁配筋进行计算，并绘制楼梯遍地配筋图。

第十步：基础设计，第一对所给的工程地质条件进行地基处置，然后对基础进行布置和截面配筋计算。具体的设计内容和设计进程将在正文中作详细说明关键词：框架结构；结构分析；抗震设计

Abstract

It locates the region of XXXX，the earthquake establishes to defend strong degree as 8 project adopts frame are three storys in the height of the floor m. The general height is and the general area of the building is 4019 square meter.

The general design thinking:The two directions of main shaft in building structure difference consideration horizontal seismic role，the horizontal seismic role of each direction should fight side force structure completely by this direction to the approximation of frame structural calculation beg to take affact untie to erect under load role force press without side move rigid frame use curved distance twice distribution law，beg horizontal earthquake to take affact under force press triangle distribution use D value related principle that uses reinforced concrete finally carries out component to match tendon calulation and school nucleus.

The concrete design stage divides into ten steps:

The first step :Load statistics，including each layer permanent year and work to carry，each building layer gravity load representative of calculation worth.

The second step:rigidity calculation include the line rigidity of each beam and colume，colume fight the D value law calculation that side rigidity D analyses according to frame.

The third step:Frame from the calculation of the earthquake period.

The fourth step:the side of Checking computation is moved，includs top displacement between layer displacement.

The fifth step:Force calcultion get each colume end with on the contrary curved a litter method to bend distance and beam end curved distance and beam end cut force.

The sixth step:Erect to the force calculation in force role sill curved rules，distribute law twice，and bend rules amplitude modulation for beam end，the coefficient of amplitude modulation β take .

The seventh step:Synthesize to match tendon with horizontal seismic force with erect under force role difference beg make force carry out unfavorable combination，some groups of unfavorable combinations that basis gets again carries out frame beam respectively，column match tendon calculation，take the biggest value in which is last match tendon.

The eighth step:Use CAD software to draw one pin frame match tendon picture and floor match tendon picture as well as beam colume section match tendon picture.

The ninth step:Stairs design matches tendon according to the definite staris parameter in building design，for platform beam，platform board and the ladder section board of stairs to carry out calculation，and draw each place of stairs to match tendon picture

The tenth step:Basic design frist carries out foundation handling for the project geological condition given，is then arranged for foundation with section match tendon calculation.
