【 摘 要 】

Based on the SeismoStrcut model of full-scale, four-story, 2D infilled reinforced concrete frame, this paper set the infill walls at different locations in the structure to obtain vertical stiffness irregular frames with weak layer. The displacement response of different weak layer frames is studied by input the same seismic waves. The results show that the vertical stiffness of the infill wall frame structure will greatly affect the response and interlayer drift. The displacement of concrete frames contains weak-layers is lager than the common ones. When the bottom layer has no infill wall, the top displacement is larger than other cases. The presence of the infill wall can limit the interlayer deformation of the frame structure.
