摘要此次设计主要对框架结构中各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。用PKPM进行电算,然后把电算结果和手算结果对比分析。52591

Abstract

The design of the main structure of the framework for each axis transverse frame structure design, seismic design and structural calculations. 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.Electrically with PKPM count, then comparative analysis the electric calculated results  with hand-calculated results .

Keywords: frames structural ,structural design, internal force calculation , reinforced calculation
