摘要本文的毕业设计主要进行钢筋混凝土框架结构的整体设计，设计主要包括建筑设计和结构设计两部分。建筑设计主要是根据任务书进行建筑功能、平面布置、立面造型以及详图设计等各部分。结构设计，主要是选取结构一榀框架进行设计，还需要对楼梯、基础以及楼板等构件进行构件设计，结构设计需要考虑安全性、经济性和耐久性。结构设计方面，首先进行结构方案与布置，选取结构类型和布置形式，估算结构构件尺寸，并计算梁、柱线刚度；根据荷载分布情况，计分别计算一榀框架承受的竖向荷载和水平荷载。再进行内力分配，对竖向荷载采用弯矩二次分配法，对计算得来的荷载进行分配；对水平荷载，采用D值法对荷载进行分配，得出各工况情况下的内力。按规范组合各内力，得出最不利值即设计值，按照结果对构件进行正截面和斜截面配筋计算。然后，分别对混凝土楼梯、结构基础、各层楼板进行构件设计。设计依据采用国家现行规范、标准和任务书。关键词：一榀框架、强柱弱梁、强剪弱弯、弯矩二次分配

结构布置结构方案与布置结构类型选择根据建筑功能进行梁、柱布置，选取具有代表性的一榀框架进行结构计算。构件截面尺寸估算1.楼板厚度混凝土设计规范要求，单向板的跨厚比小于30，双向板小于40跨厚比要求，板块跨度为3900mm，计算板厚=3900/40=97.50mm。取板厚h=100mm；对于顶层，考虑温差以及防水，取板厚h=120mm。2.框架梁截面尺寸框架梁的高度和宽度一般根据梁跨度L按下式进行计算，按规范要求，框架梁宽度一般不小于200mm，当梁跨度较小时，一般按照经验进行取值；对于次梁，其跨高比可适当增大。ℎ=以横向框架梁边跨AB为例，计算框架梁高度和宽度，过程如下：ℎ=取h=700mm；b=取b=350mm。以此类推，计算各跨和纵向框架梁尺寸，汇总结果见下表:框架梁尺寸汇总表框架梁
