Abstract
The purpose of the design is to do the anti-seismic design in the longitudinal frames of axis 2、3、7、8. 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 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 frames of the different ax (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 of the wall limbs and the coterminous girders, which will be the basis of protracting the reinforcing drawings of the components. The design of the stairs is also be approached by calculating the internal force and reinforcing such components as landing slab, step board and landing girder whose shop drawings are completed in the end. Key words： frames, structural design, anti-seismic design

摘要
本设计主要进行了结构方案中横向框架 2、3、7、8 轴框架的抗震设计。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振周期，进而按 底部剪力法计算水平地震荷载作用下的大小，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（恒载及活荷载）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。此外还进行了结构方案中 的室内楼梯的设计。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。 关键词： 框架 结构设计 抗震设计
