摘要
本工程结构为五层现浇钢筋混凝土多层框架结构。设计使用年限为50年；结构安全等级为二级；抗震设防烈度为7度；设计基本地震加速度值为0.10g，第二组；框架的抗震等级为三级；采用独立基础，地基基础设计等级丙级；建筑室内外高差450mm，室外标高即为现有自然地面标高。
根据建筑设计和结构承重、抗震方面的要求以及场地地质条件，合理地进行结构选型和结构整体布置，确定各种结构构件的尺寸，选取一榀主要横向结构框架进行结构设计计算，用计算结构力学程序对该榀结构框架进行电算与手算结果进行对比分析；完成楼梯设计和基础设计；用PKPM软件对整栋框架结构进行PKPM电算；绘制出相关建筑和结构施工图。
通过本模拟设计，可使学生综合土木工程专业各课程的知识，了解建筑设计方法，熟悉结构设计与分析过程。
关键词：弯矩、剪力、配筋、抗震
第一章 设计资料及要求
1.1设计依据
1、工程概况
本工程位于成都市，该工程为成都市阳光职业高中教学楼，采用钢筋混凝土框架结构体系，横向3跨，中间跨度为3.2m。房屋总高约19m，共5层，建筑场地约48 m *19m。根据勘察报告，工程场地条件较好，属于Ⅱ类场地土。
2、气象资料
按《建筑结构荷载规范》GB5009-2012取值。
3、工程地质资料
（1）根据勘测报告，拟建场地地势平坦，表面为杂填土；无液化土层分布，稳定地下水位埋深0.72-1.14m，对钢筋混凝土无侵蚀性。
