考虑楼板变形影响底层框架抗震墙砖混结构的地震反应分析

Earthquake Response Analysis of Masonry Buildings with Frame-Shear Wall Structures in the First Floor Considering Floor Deformation

采用串并联多自由度体系进行底层框架抗震墙砖混结构地震反应分析 ,以考虑楼板变形的影响 ,假定各榀抗侧力结构和楼板均以剪切变形为主。计算结果表明底层抗震墙的布置对底部各层特别是过渡层砖墙的地震反应有较大的影响。

In order to study the effect of slab deformation on the response of masonry buildings with frame shear wall structures in the first floor, earthquake response analysis is carried out according to model of muticolumns mutimasses system. It is assumed that all vertical members and floors of the structure are shear type deformation. The results show that the layout of shear walls in the first floor has great influence on the earthquake response, especially the response of the transitive storey.
