摘 要 此次设计主要对框架结构中⑨轴横向框架进行结构设计、抗震设计和结构计算。在确定框架结构的承重方案及计算简图之后，首先计算框架结构的层间荷载代表值，利用顶点位移法求出横向框架的自振周期，并使用底部剪力法计算在水平地震荷载作用下横向框架的层间剪力，进而求出在水平地震荷载作用下框架结构的内力（弯矩、剪力和轴力）；其次，采用弯矩二次分配法对在竖向荷载（恒荷载和活荷载）作用下框架结构的内力（弯矩、剪力和轴力）；再次，采用D值法计算水平风荷载作用下框架结构的内力（弯矩、剪力和轴力）；最后，对在水平和竖向荷载作用下框架结构的内力进行组合，找出一组或几组最不利的内力组合，并按最不利组合进行截面设计及配筋计算。另外，还对框架结构中的现浇钢筋混凝土楼板、楼梯和基础进行截面设计和配筋计算。 关键词：框架结构，结构设计，内力计算，配筋 mprehensive Teaching Building of Adult Education College of Qinghai university ABSTRACT The purpose of the design is to do the anti-seismic design in the longitudinal frames of axis 9. 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. Key words: frames，structural design，Internal force calculation，deploy Reinforced 目 录 1 建筑设计 1.1 建筑设计说明： 1 1.2 建筑方案 1 1. 2.2建筑设计做法 1 1.2.3材料选用 1 2 结构设计计算 2.1．框架计算简图及梁、柱抗侧刚度 3 2.1.1 确定计算简图 3 2.1.2框架梁柱线刚度计算 3 2.2.恒活荷载计算 4 2.2.1．恒载标准值计算 4 2.2.2 活荷载标准值计算 7 2.3框架所受竖向荷计算 7 2.3.1 A-B轴间框架梁 7 2.3.2 B-C轴间框架梁 9 2.3.3 C-D轴间框架梁 9 2.3.4 A轴柱纵向
