土木工程本科毕业设计--某办公楼框架结构设计.doc

某 办 公 楼 框 架 结 构 设 计 内容摘要 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周期，进而按底部剪力法计算水平地震荷载作用下大小，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。 结构设计 抗震设计 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 axis. Then the internal force (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. Keywords : frames, structural design, anti-seismic design 毕业设计进度计划安排: 第一周 课题调研，选题、结构方案设计 复习结构设计有关内容，借阅相关规范及资料 导荷载、计算楼层荷载 计算结构自震周期、水平地震作用大小 水平地震力作用下的框架内力分析、计算 竖向荷载作用下的框架内力计算 框架内力组合分析、计算 义务劳动周 楼层板配筋、框架梁配筋及构造 框架柱配筋、框架节点配筋及构造 TBSA计算及分析 楼梯计算，整理计算书 翻译科技资料，画图 打印论文，准备答辩 录 第一部分：工程概况…………………………………………………………1 建筑地点、建筑类型、建筑介绍、门窗使用、地质条件 ……………………1 柱网与层高 ………………………………………………………………………1 框架结构承重方案的选择 ………………………………………………………2 框架结构的计算简图 ……………………………………………
