摘 要

本设计为综合办公楼设计，采用钢筋混凝土框架结构,建筑面积6500m2，抗震设防烈度为7度，设计基本地震加速度为0.15g，基本风压为0.4kN/m2。本设计主要进行了结构方案中横向框架A，B，C，D轴框架的设计。结构设计选取一榀框架为计算单元进行计算。在确定框架布局之后，选取横向4轴框架进行计算。先用D值法计算风荷载作用下的结构内力,再用底部剪力法计算水平地震荷载作用力大小。采用D值法求出在水平地震荷载作用下的结构内力（弯矩、剪力、轴力）。接着内力组合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。还进行地基设计。此外还进行了结构方案中的楼梯的设计。完成了平台板，梯段板，平台梁等构件的内力和配筋计算及施工图绘制。

The design for the Office building in Yan an city, reinforced concrete frame structure with a building area of 6500m2, the seismic intensity of 7 degrees, the basic seismic design acceleration 0.15g, the basic wind pressure is 0.4k

kN/m2. The structure of the design of the program main horizontal frame A, B, C,

D axis frame design. Select a frame structure design for the calculation of unit frames are calculated. In determining the framework of the layout, the selected horizontal 4-axis frame is calculated. First calculated with the D value of the structure under wind load internal forces, and then the bottom of the shear force method to calculate the size of the level of seismic loading. Value calculated using D seismic loads in the level of the structure of internal forces (bending moment, shear, axial force). Then find the most unfavorable combination of internal forces of a group or several groups of internal force combination. Select

the most secure on the results of reinforcement and graphics. Also for foundation design. In addition to the structural design of the staircases in the program. Completion of the platform board, bench plates, platforms and other components of the beam deflection calculation and construction drawing.

Key words: seismic intensity, the internal force composition, framework, D value method
