摘 要关键词：Abstract This is a teaching building of a Dongxu chool in shenyang. It is a multi-layer reinforced concrete frame. It has five stories, the height of the first storey is 3.6 meters, and the height of other stories are a 3.6 meters to. The height of the whole building is 18.9 meters. In accordance with the design principle of “applicability、safety、economy、aesthetic”and the present codes and standards of the architectural and structural design, the primary architectural and structural design of building is carried out. After getting the architectural drawing from CAD design, the anthor decides the structural scheme and the structural calculation model When the directions of the frames is determined, firstly the weight of each floor is calculated . 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，axial force ＆snow 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.The design of floorslab is also be completed in the end. 　　　　　　　　 Keywords: reinforced concrete；frame； the design of the structure 引 言 1 建筑方案设计 1.1 工程概况 1.1.1 建筑设计指标 1.1.2建筑设计思路框架结构的最大特点是承重构件与围护构件有明确分工，建筑的内外墙处理十分灵活，应用范围很广。根据框架布置方向的不同，框架体系可分为横向布置、纵向布置及纵横双向布置三种。1.2 建筑构造设计 1.2.1非上人屋面构造设计［1］ 1) 25mm厚1﹕3水泥砂浆 2) 40mm厚SBS改性沥青防水卷材 3) 20mm
