超静定问题
In order to solve the problem that the internal force of statically indeterminate prestressed and reinforced concrete bar system structures is difficut to determine when the structures come to the non-elastic state, a simple analysis method of experimental structures' internal force-sectioned dropping rigidity method is brought forward.
针对预应力混凝土和钢筋混凝土超静定杆系结构试验中进入非弹性状态后的结构内力难以准确测定的事实,本文提出了一种用于试验结构内力分析的简化方法&分段降刚度法。
