1、摘要本设计为徐州市海达集团行政办公楼设计，主体为5层框架结构，局部6层。包括建筑设计和结构设计两部分。建筑设计包括建筑的平面图，立面图，剖面图，楼梯详图以及建筑说明图。结构计算内容有荷载计算，内力计算，内力组合，截面计算，板、楼梯、基础设计等几方面。在确定计算简图之后，选取一榀框架进行计算，进行了重力荷载代表值的计算,通过顶点位移法求出自振周期，按底部剪力法计算水平地震荷载作用大小，用D值法求出在水平地震作用和风荷载作用下的结构内力（弯矩、剪力、轴力）。用分层法计算竖向荷载（恒载及活荷载）作用下的结构内力，由所得的
2、内力进行内力组合，找出最不利的一组或几组内力组合进行梁、柱的配筋计算并绘图。进行了楼板、楼梯，基础的配筋计算。屋面为上人屋面，采用双向板设计。基础采用柱下独立基础，包括荷载计算，基础承载力计算。关键词：结构设计；框架；抗震设计；楼梯；基础AbstractThisdesignfortheXuzhouHaidagroupadministrationofficebuildingdesign,themainbodyis5portalframeconstructions,partial6.Includingarchitect
