摘 要

本次毕业设计的是一幢住宅楼，位于威海的一栋住宅楼，占地面积为544m2,为现浇钢筋混凝土框架结构。设计使用年限为50年，耐火等级II级，采光等级为II级，抗震等级为三级。

主要进行的是结构设计部分：

一、结构方案阶段：根据建筑的重要性，建筑所在地的抗震设防烈度，工程地质勘查报告，建筑场地的类别及建筑的功能、高度和层数来确定建筑的结构形式，本工程采用的是钢筋混凝土框架结构；

二、结构计算阶段：包括荷载计算、内力计算和构件计算；

三 施工图设计阶段：根据上述计算结果，来最终确定构件布置和构件配筋以及根据规范的要求来确定结构构件的构造措施。

ABSTRACT

The graduation design is a residential building，The size of544 m2

Cast-in-place reinforced concrete frame structure，Design life of 50 years，Refractory grade II

The stage of the structural design can be divided into three stages on the whole:

1. Structural scheme stage: According to the importance of the building, providing fortification against earthquakes in the earthquake intensity, the geologic prospect report of the project of the building site, classification and height and storey of the building of the building field are counted to confirm the structural form of architecture, what this project is adopted is frame structure;

2. Calculate stage in structure: Including loading and calculating, the internal force is calculated and calculated with the component;

3. Construction drawings design phase: According to described above result of calculation, come, confirm component assign with component mixing muscling and coming, confirming structural structure measuring of component according to the request of norm finally.
