框支剪力墙土-结构共同作用的抗震性能分析
Antiseismic performance analysis for co-interaction of soil-structure of frame-supported shear wall
摘要
Abstract
A finite element elasto - plastic time - history analysis was conducted on the interaction system of soil - structure of frame - supported shear wall. The data of free vibration characteristics of models and the displacement, inter- storey drift angle, the ratio of equivalent lateral stiffness and shear force under earthquake were studied. The results show that, using models built in ANSYS to analyze the seismic response of SSI structure of frame - supported shear wall can efficiently reflect the seismic performance of structure. The location of conversion floor has little effect on the natural period of vibration mode. The drift angle and shear near conversion layer had mutations, which intensified with the increase of conversion layer position. The higher the level of transfer stories, the larger the ratio of equivalent lateral stiffness is. The larger inter - storey drift angle of structure occurs in middle - upper part. The maximum shear force of columns appears in the middle columns on transfer storey. The height of transfer storey can be set a little higher properly but not more than 5 layer in design. The ratio of e-quivalent lateral stiffness should be ranged between 0. 8 and 1.3. Not only should the frame - supporting columns be particularly strengthened, but also some measures should be taken to decrease the story drift in middle - upper part of structure.关键词
