摘要
常规力矩分配法将结构看作由直杆单元组成,刚架比较复杂时,结点位移较多,计算比较麻烦.本文对Γ形单元转动刚度和传递系数进行了推导,使得对某些无侧移复杂刚架应用力矩分配法求解内力工作量得到简化.
The structure is regarded as straight bars in conventional moment distribution method,and the computation is difficult when the frame is too complex and the displacement of joint is too much.In the paper,the rotational stiffness and coefficient of transmission of Γ-Shaped element are derivated,and the internal force computation is simplified for some complex non-say frame by using moment distribution method.
