摘 要
 本工程是台州市某综合办公楼。为多层钢筋混凝土框架结构。主体5层，底层层高5.5米，2至4层层高为3.6米， 5层层高4.0米。建筑物总高度为24.70m。
 本设计主要进行了结构方案中纵向框架5轴框架的设计。在确定框架布局之后，先进行了层间荷载标准值的计算，接着利用D值法计算水平风荷载的大小，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（恒载和活载）作用下的结构内力。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，最后进行了基础的设计。此外还进行了结构方案中楼梯的设计。

Comprehensive  office building in TAIZHOU

Abstract
 This is a comprehensive  office building in TAIZHOU . It is a multi-layer reinforced concrete frame. It has five stories, the height of the first storey is 5.5 meters, and the second、 third and the fourth storel is 3.6 meters ,the fifth storey is 4.0 meters. The height of the whole building is 24.7 meters.
 The purpose of this design is to  do the anti-seismic design in the longitudinal of axis 5. When the directions of the determined,firstly the weight of each floor is calculated.Then the wind load in calculated by D method,then making the amount of the horizontal seismic force can be got by way of the bottom_shear force method.The seismic force can be assigned according to the shearing stiffness of the frame of the different axis. Then the internal force (bending moment,shearing force and axis 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 Excal software,whose purpose is to find one or several sets of the most adverse internal force of the wall limbs and the coterminous girders,which will be the basis of protrating the reinforcing drawings of the components.The design of the stairway is also be approached by calculating the internal force.
