摘 要
本工程是教学楼,共五层，底层4.2m，其他层高均为3.6m，建筑面积为5177.12m2,建筑总体布置为一字形，结构为现浇钢筋混凝土框架结构，抗震设防烈度为6度，抗震等级为三级。结构设计时取一榀具有代表性的框架进行设计，活荷载计算采用三种不利组合，水平地震作用采用底部剪力法计算。内力计算中恒荷载作用采用迭代法进行计算，活荷载采用分层法进行计算，水平荷载作用采用D值法进行计算，内力组合考虑非抗震组合和抗震组合。截面设计时考虑“强柱弱梁、强剪弱弯”的原则进行内力调整，最后进行了楼梯设计。
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， 选取最安全的结果计算配筋并绘图。此外还进行了结构方案中的室内楼梯的设计，完成了平台板，梯段板，平台梁等构件的内力和配筋计算及施工图绘制。

Abstract
This is a teaching building of a university. It has five stories, and the height of the every storey is 3.9 meters. The building area of this engineering is5177.12 square meter, height is 19.8 meter. Building the intake workinteger arranges for L form, the structure is now to sprinkle the steel concrete framing structure, anti- the earthquake establishes to defend strong kilowatt hour as 7 kilowatt hour, anti- earthquake order is x-rated. Structural design the hour take a has the representative framing proceeds the design. In the calculation of internal forces,permanent load function uses iterative method o carry on the computation , while variable load uses the delamination to carry on the computation，level quake function adoption the bottom shearing force logarithm of timw fitting method logt computes, inner force computation inside perpendicular lading function adoption the layering logarithm of timw fitting method logt proceeds the computation, the level lading function adopts the worth logarithm of timw fitting method logt in D proceeds the computation, inner force articulation consider not anti- earthquake combine to shake the articulation with anti-.Cutting the hour of design considers\strong stanchion is weak curved\Finally to the stair way design
When the directions of the frames is determined, firstly the weight of each floor is calculated. 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.
Keywords : frames, structural design, anti-seismic design
