偏心结构空间杆系模型与空间实体模型的对比分析研究
|
摘要
分别用空间杆系模型和空间实体模型对偏心结构进行弹塑性时程分析,并比较两者的差别。研究发现,在结构刚进入塑性阶段时,采用空间杆系模型和空间实体模型得出的偏心结构塑性变形接近;而结构产生较大塑性变形时,采用空间实体模型得出的偏心结构塑性变形要比采用空间杆系模型得出的大许多。
A few eccentric structures are modeled with beam-column element and solid element respectively for comparison in this paper.Several nonlinear dynamic time-history analyses of the structures have been carried out with the two types of finite elements.The differences between the two finite elements are compared.It is found that the plastic deformations of the structures are close to each other at the beginning of plastic phase of the structures,but the plastic deformation obtained with the solid element is far larger than that obtained with the beam-column element when large plastic deformation is developed in the structures.
