某办公楼建筑结构设计办公楼工程框架结构毕业设计.doc

摘要
本工程为大同市某办公楼建筑结构设计办公楼工程,采用框架结构,主体为三层,本地区抗震设防烈度为7度,近震,场地类别为II类场地。主导风向为东南,, KN/m2。楼﹑屋盖均采用现浇钢筋混凝土结构。
本设计主要进行了结构方案中横向框架第9轴抗震设计。在确定框架布局之后,先进行了层间荷载代表值的计算,接着利用顶点位移法求出自震周期,进而按底部剪力法计算水平地震荷载作用下大小,进而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。是找出最不利的一组或几组内力组合。选取最安全的结果计算配筋并绘图。
总之,适用、安全、经济、使用方便是本设计的原则。设计合理可行的建筑结构方案是现场施工的重要依据。

Abstract

The Datong City in an office building in building structure design of office building, a framework structure, the main body of three layer, local seismic fortification intensity is 7 degrees, near the earthquake site classification as class II venues. The dominant wind direction to the southeast, the basic pressure , basic snow pressure KN/m2. Floor and roof of cast-in-place reinforced concrete structure.
This design mainly carries on the structure plan in the horizontal frame ninth axis seismic design. After determining the frame layout of the first layer between the representative value of the load calculation, and then demand the use of vertex dis- placement from the earthquake cycle, then according to the bottom shear method to calculate the horizontal seismic load under size, then calculated under the action of horizontal load structure internal force (bending moment, shearing force and axial force). Then the internal force of the structure under the vertical load (constant load and live load) is calculated.. Is to find the most bination of a group or a few groups of internal forces. Select the most secure results for calculation of reinforcement and drawing..
In short, the application, safety, economy, ease of use is the principle of this design. The reasonable and feasible construction scheme is the important basis for field construction..
