摘要

本毕业设计工程是武汉市某小区里的商住楼，包括建筑设计和结构设计两部份内容。

一、建筑设计是在整体计划的前提下，依照设计任务书的要求，综合考虑建筑物与周围环境、建筑物的利用功能、流水交通及经济性等问题，依据有关设计标准来确信设计方案，做出建筑的结构形式、建筑平面、剖面及立面设计。

二、结构设计是在建筑物初步设计的基础上确信结构方案；选择合理的结构体系；进行结构布置，并初步估算，确信结构构件尺寸，进行结构计算。在确信框架布局以后，我先进行了层间荷载代表值的计算,接着利用极点位移法求出自振周期，进而按底部剪力法计算水平荷载（地震荷载、风荷载）的作用，求出在水平荷载作用下的结构内力（弯矩、剪力、轴力）。接着计算竖向荷载（恒载及活荷载）作用下的结构内力，并利用Excel表格找出最不利的一组或几组内力组合，选取最平安的结果计算配筋。另外还进行了基础、楼板及楼梯的设计，利用PKPM电算软件对整体结构进行分析，并绘制相关的结构施工图。

Abstract

This engineering graduation project includes two parts--- the architecture design and the structure design of a district in Wuhan in commercial and residential building.

1. The architecture design is made under the premise of the overall programming, according to the request of the design mission, in addition, the building and its surroundings, usage function, the transportation and architecture economy and so on are compressively considered. And the project design according to the related design norm confirm the structural form of architecture, the design of the plan views ,the elevation views and the sectional views.

2. The structure design is based on preliminary architecture design, to select the right structure type, precede structure arrangement and sizes of structure components to calculate. When the directions of the frames is determined, firstly the weight of each floor is calculated .Then the vibrate cycle is calculated by utilizing the peak-displacement method, then making the amount of the horizontal load force (seismic load，wind load) can be got by way of the bottom-shear force method. The force can be assigned according to the shearing stiffness of the frames of the different axis. Then the internal force (bending moment, shearing force and axial force ) in the structure under the horizontal loads can be easily calculated. After the determination of the internal force under the dead and live loads, the combination of internal force can be made by using the Excel software, whose purpose is to find one or several sets of the most adverse internal force ，which will be the basis of protracting the reinforcing drawings of the components. Beside that, The designs of the foundation、floor slabs and stairs are also be approached by calculating the internal force and reinforcing . We can use the computer software PKPM to analysis the overall structure. After all，the construction drawings are completed.
