- In order to study the seismic performance of masonry buildings with frame and seismic-wall in the lower stories, a serious damaged bottom frame structure in Wenchuan earthquake was taken as the research object in this paper. The eccentricity of each layer of the structure was calculated, and seismic damage prediction method was used to judge the weak floor of structure. Elastic time- history analysis and numerical simulation were carried out on the use of ABAQUS finite element software. Calculation results show that: at the bottom layer of the structure with excess reinforced concrete anti-seismic wall and filled wall, the stiffness and the resistance is greatly increased, and that makes the weak floor of the structure transfers from the bottom layer with better ductility and energy dissipation to the second layer of masonry floor. Also under the horizontal earthquake action, the whole structure especially the first floor has obvious torsional coupling response, also increases the damage of the second layer, eventually leading to the destruction of the whole structure.
