摘要
设置水平加强层可以降低由裙梁柔性导致的框筒剪力滞后效应,增强结构空间受力性能,提高结构抗侧刚度。通过对若干算例进行空间有限元分析,讨论了加强层的刚度、布置状况等对外框筒剪力滞后效应、结构抗侧刚度等的影响,并提出了加强层设置的建议。
The shear lag effect of frame-tube structures caused by the flexibility of the spandrel beam can be weakened by setting outriggers. At the same time the spatial performance and lateral stiffness of the structure are also enhanced. By analyzing several schemes using spatial finite element method, the influence of the stiffness and arrangement of outrigger on the shear lag effect of the outer frame-tube and lateral stiffness of the structure is discussed, and some advices of the layout of outrigger are put forward.
