某某中学男生宿舍楼设计.doc

摘 要 本设计的题目为某中学男生宿舍楼设计。建筑主体八层，每层层高均为3.3m，建筑总高度为29.40m，总建筑面积为6622.88㎡，抗震设防烈度为7度，抗震等级为三级，结构采用钢筋混凝土框架结构。 本设计主要进行了结构方案中横向框架A、B、C、D轴框架的抗震设计，其中由于结构的对称性，只对A、B跨进行了细致的分析计算，由对称性可以知道A、B、C、D整个框架的数据。在确定框架布局之后，先进行了层间荷载代表值的计算,接着利用结构抗震中的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 抗震设计 内力组合 配筋计算 Abstract The title of this Project is designing for a conglomerate storied building of some High school of the bull pen building.The architecture has eight stories.Its every 3.3m high and its top is 29.40m .Its whole floorage is 6622.88㎡. The earthquake intensity is 7. Its Seismic grade is 3.0 Style of the building is totally frame structure of reinforced concrete. The purpose of the design is to do the anti-seismic design in the longitudinal frames of axis A、B、C、D.Because of the symmetry of the frame structure,it can have the result according to careful analysis and calculation . 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 which is come from Structure seismic, 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 calcu
