摘要
位移法是求解超静定结构的基本方法,文献介绍一般常规位移法基本体系由直杆单元所组成,刚架比较复杂时,基本未知量较多,计算比较麻烦.本文通过对等截面直角折杆刚度方程的推导,使得对某些无侧移复杂刚架应用位移法求解内力工作量得到简化,并通过实例验证了其适用性.
Displacement method is the basic method to compute the statically indeterminate structure.It was introduced in some literatures that the basic system of conventional displacement method was composed of straight bars,and there were a bit more basic unknown variables,and the computation would be difficult when the frame was too complex.The stiffness equation of uniform cross section rectangular fold bar was derivated in the paper,and the internal force computation was simplified to complex nn-say frame using displacement method.In the end,the feasibility was verified by an actual case.
