1、 - 1 - 内容摘要内容摘要 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。在 确定框架布局之后，先计算了恒载，活载，风载的等效荷载以及各杆端的内 力，然后用分层法进行内力分配，然后各层叠加，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。 关键词：关键词： 框架框架 结构设计结构设计 内力组合内力组合 Abstract The purpose of the de
2、sign is to do the anti-seismic design in the longitudinal frames of axis A， B， C， D， E， F. 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 ho
3、rizontal 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 axis. Then the internal force in the structure under the horizontal loads can be easily calculated. After the determination
4、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 re
5、inforcing 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.
