摘　　要：超长钢筋混凝土框架在温度应力作用下的分析很复杂 ,当求得柱顶侧移后 ,用A值法计算杆端弯矩 ,然后可得出剪力、轴力。实质上A值法为在水平力作用下的一次位移分配法 ,计算简便 。It is very complicated to analyse temperature stress in ultralong reinforced concrete frames.After calculating sidesway of the top of columns,the end moment of memders can be obtained by A value method.Then the shear and axial forces of the frame can be obtained too.In substance, A value method is a once displacement distribution method for analyzing frames subjected to horizontal forces.This caculation method is simple,and its accuracy is very high.
