摘要在实际工程中,钢筋混凝土框架结构是一种较为普遍结构形式,广泛应用于住宅、办公、学校等公共建筑。本设计五层框架结构,首层层高3.9m,其他层层高为3.6m。总高度为19.35m。建筑总面积为4600m2。为抗震等级三级,7度设防,建筑场地为二类。利用Auto CAD及天正建筑对教学楼进行了平面、立面、剖面即整体布局的建筑设计。52577
在进行设计时对结构的恒载、活载、风荷载以及地震荷载进行计算。竖向荷载利用分层法、水平荷载利用D值法进而得到各种作用下结构各杆件的内力标准值。然后按照最不利组合方式,对各种作用下的内力进行组合。最后在组合中找出各杆件最不利的一组或几组对构件进行截面设计,选取最安全的结果进行配筋并绘出施工图。本设计还对基础、楼板、楼梯等进行了设计,并绘出了结构施工图。除对本框架进行手算外,还利用了PKPM对本结构进行了电算。

Abstract
In practical engineering, the reinforced concrete frame structure has been a common structural form owing to their successful applications in many areas such as residence, office, schools and other public buildings. The store is 3.9m . The total height of 19.35m .The total building area of this project is 4600m2.For three level of earthquake framework, 7 degrees fortifications, near site classification as Class two venues.This design including the architecture design and structure design, using Auto CAD and it is building, on the teaching building for the plane, elevation, section whereby the overall layout design.
This thesis is aimed at the design for transverse frame of teaching buildings with multistory frame. First, dead loads, live loads, wind load and seismic load of the structure are computed referring to “Load Standards ”. Then the standard values of each members of structure under horizontal load and vertical load can be obtained by using stratification method and “D” method respectively. Next, the internal forces under various load are combined according to the most unfavorable combination mode. Finally, the most unfavorable one or several ones in the above combinations to realize section design for members is found. In this way, the safest results to reinforce is chosen and Working Drawing is Painted. the basement, the floor and the stairs are also designed and structural working drawing are painted in this thesis. Moreover, the structure computerization is shown via employing PKPM.
