摘要本工程为某购物中心,三层的框架结构,层高为4.2m,总高度为13.6m,建筑总面积为4614.57m2。因为该工程抗震设防烈度为7度, ,所以不考虑竖向地震作用。在用底部剪力法求出水平地震作用后,利用D值法完成了水平地震作用下的一榀框架的内力组合计算。采用弯矩二次分配法分别完成了恒载和活载最不利布置作用下的内力计算。接着进行结构构件的地震作用效应与其它荷载效应的基本组合及无地震作用效应与其它荷载效应的基本组合两种情况,对框架内力进行组合,得出框架梁柱的控制内力,进而完成了梁柱截面的配筋计算。进行了独立基础的计算及零星构件的计算。用天正2008、AutoCAD2007、PKPM2008软件等计算并绘制本工程建筑和结构施工图。52574

Abstract
This project is a shopping center, a three-tier framework, the height of 4.2m, a total height of 13.6m, total construction area of 4614.57m2. Because the project seismic intensity of 7 degrees, so I do not consider the vertical seismic effect. In the base shear method determined by the level of seismic action after the completion of the D value method under horizontal seismic forces framework of a combination of specimens of calculation. Moment Distribution Method were used to complete the dead load and live load under the most unfavorable arrangement of the internal force calculation. Followed by a seismic effect of structural members and other basic combination of load effects and no seismic effect and other basic combination of load effects both cases, the combination of the framework forces, drawn frame beam control forces, and then complete the beam reinforcement Calculation column section. Conducted an independent member-based calculation and sporadic calculations. With Tengen 2008, AutoCAD2007, PKPM2008 software engineering calculations and draw the architectural and structural drawings.
Keywords: earthquake, frame structure, double-moment-pided method, load effect combination
