摘要本课题是设计某多层框架结构办公楼，在计算书中主要对结构方案中横向框架○2轴线进行了抗震设计。在完成框架布局后，先求出了框架各层恒、活和重力荷载代表值，并用二次弯矩分配法求各个竖向荷载作用下的结构内力（弯矩、剪力、轴力），接着计算了风荷载和地震作用下的水平荷载。其中，地震作用下的水平荷载是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，并在此水平荷载作用下计算结构的内力。然后通过一组或几组内力组合找出结构的最不利位置，选取最安全的结构计算配筋并绘图。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，楼梯段，平台梁等构件的内力和配筋计算）、楼盖的设计（完成板的配筋）、基础的设计（完成了独立基础的配筋及基础平面图）52500

Abstract This topic is the design of a multi-storey building frame structure, and the purpose of design is to do the anti-seismic design in the longitudinal frame axis. At the completion of layout after the first frame, the frame constant, live and representative value of gravity load, and the structure internal force of each vertical load of the two bending moment distribution method (moment, shear, axial force), then the effect of horizontal load of wind and earthquake are calculated under. Among them, the horizontal load under the action of earthquake is the use of vertex from the displacement method for earthquake cycle, and then at the bottom of the shear horizontal seismic load calculation under size, internal force and the horizontal loads calculation of structure. Then find the most disadvantaged position structure by means of a group or several groups of internal force combination, select the most secure structure reinforcement calculation and drawing. In addition, the design of the stairs is also carried out (the completion of a platform board, stairs, platforms and other components of the beam internal force and reinforcement) design, floor (complete board reinforcement) design, foundation (completed independent foundation reinforcement and foundation plan).
