1、摘 要 毕业设计内容主要包括两大部分：第一建筑方案设计；第二结构设计。包括粱，柱，楼板，楼梯，基础结构。结构设计主要进行了结构方案中横向框架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。 最后应用CAD软件画出设计的建筑和结构图。然后截面强度验算，包括预应力配筋计算、承载力极限状态验算、正常使用极限状态验算、应力验算等，通过计算可以验证该建筑各项指标都满足规范
2、要求。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最新的国家标准规范，对设计的各个环节进行综合全面的科学性考虑。总之，本着安全，适用，美观和节约的原则进行设计。主体五层，采用内廊式主体结构，整个建筑外形呈槽型字形布置，与周围其他建筑相互协调，既保持了足够的间距满足采光通风要求也体现了美观。在结构方主要采用砌体结构，局部加设独立柱和大梁，采用横墙承重方案，充分考虑大空间教室的跨度进行梁板的设计，消防等方面进行了充分考虑。关键词： 框架结构设计；抗震设计;ABSTRACTThe design content mainly includes two major parts:
3、 First construction plan design; Second structural design. Including beams, columns, slabs, stairs, foundation structure. The purpose of the structure design is to do the anti-seismic design in the longitudinal frames of axis 8. When the directions of the frames is determined, firstly the weight of
4、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
5、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
6、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.The last application of CAD software to draw a diagram of the design of buildings and structures. Then the cross-section strength calculation , including pres
7、tressed reinforcement calculations, bearing capacity limit state checking , the normal use of the limit state in design and stress check can be verified by calculating the indicators of the building to meet the specification requirements . The entire structure in the design process, strictly follow
