摘要：本毕业设计题目是XX花园7#6层住宅设计，该办公楼的总建筑面积大约是2500平方米，共六层，建筑高度为20.4米。本建筑采用钢筋混凝土全现浇框架结构体系。

    本设计内容包括手算和电算两部分。其中手算部分分计算书的主要内容为设计的总说明、构件尺寸的初步确定、框架的计算简图、荷载计算、框架横向侧移计算、框架在水平及竖向荷载作用下的内力计算分析和计算、内力组合、截面设计及基础设计。其中计算水平地震力作用下时采用极限状态设计方法。

    电算时，先用PMCAD软件进行结构平面布置，检查平面数据，输入次梁楼板，输入荷载数据，形成PK文件，画结构平面图，然后使用PK进行框架计算；最后用SAT-8软件进行框架的空间结构计算，输出框架梁柱配筋梁。柱配筋图及内力计算结果。

    结构设计的阶段大体可以分为三个阶段：

    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高度和层数来确定建筑的结构形式，本工程采用的是框架结构；

    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

    在设计过程中采用了手算和电算两种方式，对计算结果进行校核，及时发现设计中的错误以及与电算不同的部分，找出原因。

Abstract：The theme of this graduation design is structure design of Blu-ray group office .The total building area is about 4500 ㎡and the total height is 20.4m .It consists of 6 stories .The building is a frame building made by reinforced concrete.

The content of this design include two aspects of handworker counting and automated counting by computer.The handworker counting consists of several loads counting,lateral displacement counting of transverse frame ,internal force of section and check design of the foundation.

  Horizontal earthquake counting use the underlying shears way.Counting of vertical loads bending moment use double divided bending way.Design of section use ultimate condition way.

  First,make a model of the building by PMCAD;Second,count the typical frame by PK;Last ,count the whole space frame and put out the drawing that you wanted by SAT-8.

  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.

  I use two kind of ways included handwouker and automated counting in the course of counting.So I can check the result data and find the mistake or difference between handworker data and automated data in the design in time ,then find out the cause .

Key words：Graduation design，Frame structure，Load combinations，Section design
