5层框架结构办公楼结构设计 摘 要 本设计为一栋5层框架结构办公楼。在本设计中，主要进行了结构方案中横向框架5轴的抗震设计。在确定框架布局方案之后，首先根据设计资料进行了楼盖、屋盖以及次梁的设计，接着进行了结构方案中的室内楼梯设计，进而进行层间荷载代表值的计算，并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剪力的大小，进而求出在水平地震作用下的结构内力。接着计算竖向荷载作用下的结构内力并进行内力组合，选取最不利的组合进行计算配筋并绘图。此外，本设计还进行了基础承台和预制桩的设计，同时进行配筋计算和施工图的绘制。 关键词：钢筋混凝土；框架；结构设计；抗震设计；桩基础 Abstract This design is finished for an office building which is a five stories frame structure. The purpose of the design is to do the anti-seismic design in the longitudinal frame of axis 5. When the directions of the frames is determined, firstly according to the design data, the floor slab and second beam are designed, as well as the stairs. Then the weight of each floor 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 axis. Then the internal force in the structure under the horizontal loads can be easily calculated. After the determination of the internal force can be made, whose purpose is to find the most adverse internal force to be the basis of protracting the reinforcing drawings of the components. The design of the pile foundation is also be approached by calculating the internal force and shop drawings are completed in the end.
