Firstly, an equivalent structure with cyclic periodicity is built. The rigidity damage of the bar can be expressed as an additional loading in the governing equations of a substructure. Then, by using the U-transformation technique, the equations may be uncoupled into independent equations. The nodal displacements are solved in the analytical form. Lastly, a calculation example is taken, and the obtained nodal displacements are compared to the those of a perfect structure. It is shown that the variations of the displacements are reasonable. This paper provides a means for analyzing the influence of the rigidity damage on the plane truss structure., authors=YANG Yi, YANG Chao, XU He, authorsList=YANG Yi, YANG Chao, XU He,

articleAbstract=采用解析方法,研究了带损伤平面桁架结构的静力问题。对于含有n个子结构的平面桁架结构,建立一个与理想桁架结构等价的循环周期结构体系,对其中一个子结构建立控制方程,将杆件损伤处理为方程的荷载项,运用U 变换法对静力学方程组进行解耦,推导出各个节点位移的解析表达式。应用解析表达式分析带一个杆件损伤桁架结构的节点位移,并与无损伤时结构的解相比较,结果显示,有损伤时相关节点位移较无损伤时有所增大,且其位移变化合理,验证了解析表达式的可行性。, authors=杨怡, 杨超, 徐赫, authorsList=杨怡, 杨超, 徐赫, authorCompany=华南理工大学土木与交通学院,
