| 摘 要： | 通过ANSYS软件建模计算，研究了水平地震作用下筒体结构剪力滞后现象的特点和规律，分析了基础隔震对筒体结构剪力滞后效应的影响。研究结果表明：水平地震作用下，筒体结构出现了明显的剪力滞后现象，随着楼层高度的增加，滞后效应逐渐减弱，直至出现负剪力滞后；基础隔震可明显改善筒体结构的剪力滞后效应，且使首次出现负剪力滞后效应的位置降低；不同地震波作用时，剪力滞后程度不同。

| Abstract: | By using the finite element analysis software ANSYS, this paper discusses the characteristics and changes of the shear lag in the horizontal seismic wave action, and analyzes the effect of the base isolation on the shear lag effect of the tube structure. The results show that under the action of horizontal earthquake waves, tube structure appears obvious shear lag effect, with the increase of the height, shear lag gradually weakenes until the negative shear lag appears; base isolation can obviously improve the shear lag effect and make the first position of appearing negative shear lag effect lower; under the different earthquake wave action, the degree of shear lag is different. |
