1.2设计内容和要求

1. 毕业设计的意义

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。

1丶建筑部分

根据柱网要求和建筑功能要求等进行建筑设计，并完成相应的建筑施工图绘制。

2结构部分

1）进行结构布置，选择构件截面尺寸及材料标号。

2）对下列结构、构件进行设计计算：

（1）一榀横向框架：荷载计算（包括地震作用），要求手算；内力分析，其中恒载、地震作用手算，活载（考虑不利布置）、风荷载上机计算；内力组合与梁柱截面设计，需手算底层、标准层和顶层；其余各层由软件计算。

（2）现浇楼面板：任选一层手算，其余各层软件计算。

（3）楼梯设计：任选一层楼梯手算，其余软件计算。

（4）基础设计：完成基础选型、平面布置，基础设计计算。

3）绘制施工图：建筑部分图量不少于A1或A2图纸6张，原则上不多于10张图纸。施工图中均应有施工说明。
