1、摘要本设计综合运用所学的专业知识，根据设计任务书的要求进行了钢筋混凝土结构办公楼的建筑设计和结构设计。建筑设计依据建筑总体规划要求、建筑用地条件和基地周边的环境特点，依次进行平面设计、立面设计、剖面设计及细部构件设计。结构设计以现行的有关规范为依据，密切联系建筑设计。在本设计中以框架结构中⑦轴横向框架为例进行内力计算、内力组合和结构构件配筋计算。首先确定框架结构的承重方案及计算简图，计算框架结构的层间重力荷载代表值，其次用底部剪力法计算水平地震荷载作用下横向框架的层间剪力，进而采用D值法求出水平地震荷载作用下框架结构的

2、内力。同理计算水平风荷载作用下框架结构的内力；然后采用分层法计算竖向荷载作用下框架结构的内力；最后，把水平荷载和竖向荷载作用下一棉框架的内力进行组合，找出最不利的内力组合，按最不利组合进行截面设讣及配筋计算,并进行抗震验算。另外，还对框架结构屮的现浇钢筋混凝土楼板、楼梯和基础进行截面设计和配筋计算。关键词：框架结构，内力组合，结构设计，抗震设计，配筋计算ABSTRACTThisdesignusestheprofessionalknowledgesyntheticallyaccordingtotherequestofth
