摘　　要：20世纪70年代后我国住宅主要采用砌体结构,由于混凝土预制空心楼板承载力普遍偏低,至今多数老旧小区已达到或超过使用年限,因空心楼板资料缺失,承载力不明。对此采用非线性有限元软件ABAQUS对预制空心楼板的加固方法进行数值模拟分析,根据模拟结果得出了最优加固方案。Most domestic residential buildings in China after 1970s are masonry structure. The bearing capacity of prefabricated concrete hollow floor slab is low and these buildings in most old communities have reached or exceeded their service life. Information about the hollow floor slab is unavailable, so the bearing capacity could not be determined. Therefore, nonlinear finite element software ABAQUS was used for numerical simulation analysis on the prefabricated hollow floor slab reinforcing method, and the best reinforcing method was selected according to the simulation result.
