PAGE PAGE IV PAGE 1 摘 要 本设计的题目为陕西科技大学宿舍楼公寓设计。建筑主体六层，总建筑面积为5045m2，建筑总高度为20.40m，抗震设防烈度为8度，抗震等级为三级。结构采用钢筋混凝土框架形式及独立的钢筋混凝土柱下基础。 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。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。 整个结构在设计过程中，严格遵循相关的专业规范的要求，参考相关资料和有关必威体育精装版的国家标准规范，对设计的各个环节进行综合全面的科学性考虑。总之，适用、安全、经济、使用方便是本设计的原则。设计合理可行的建筑结构方案是现场施工的重要依据。 关键词： 框架结构，抗震设计，荷载计算，内力计算，计算配筋 Abstract The title of this Project is designing for a conglomerate storied building of NO.11Middle School’s apartment block in the city of ChangChun. The architecture has six stories and. Its whole floorage is 5045m2, its top is 20.40m high. The earthquake intensity is 7. Style of the building is totally frame structure of reinforced concrete. The foundation of the building is the single footing stand. The purpose of the design is to do the anti-seismic design in the longitudinal frames of axis A、B、C、D. 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 r
