采用剪力墙体外加固中小学校框架结构抗震性能研究
Study on Seismic Behavior of Middle and Primary School Frame Structures Retrofitted with External Shear Wall
摘要
Abstract
External strengthening has the Advantage of arbitrary adjustment, function without interruption and strong integrity,it is a excellent reinforcement scheme which is adopted in frame structure to enhance its seismic performance in middle and primary school. External strengthening with shear wall is applied to a 4-layer frame structure of a school building which could not meet the seismic requirements in this paper. Flexibility and elasto-plastic seismic response of the structure were analyzed by different reinforcement methods, and seismic behavior of the structure under different reinforcement was studied, the main parameter is the width of shear wall. The analytical results show that the seismic force of every pin frame retrofitted reduced obviously, the decline is greater as the shear wall is wider, and angular displacement of the floor tends to uniformity. The developments of plastic hinge of retrofitted frame are postponed comparing these of original frame. Based on the analysis results, some design suggestions of external strengthening with shear wall for frame structure is proposed.关键词
