摘　　要：农村已建老旧房屋以无圈梁构造柱的砌体结构为主,提高其抗震性能成为亟待解决的工程问题。提出外贴预制圈梁构造柱加固技术,以提高结构的整体抗震性能。对加固后墙体的损伤特性进行数值模拟和试验研究,结果表明:采用圈梁构造柱加固措施可明显提升砌体结构的抗震性能,预制和现浇两种加固方式产生的滞回变形幅值有所不同,预制圈梁构造柱加固墙体的变形幅值相对较小,变形滞回效应更为明显,抗震性能更好。The old houses built in rural areas are mainly masonry structures without ring beams and structural columns,and improving their seismic performance has become an urgent engineering problem to be solved.The reinforcement technology of externally attached prefabricated ring beams and structural columns is proposed,so as to improve the seismic performance.The numerical simulation and experimental research on the damage characteristics of the reinforced wall are carried out.The results show that the seismic performance of masonry structures can be significantly improved by the reinforcement measures of ring beams and structural columns.The hysteretic deformation amplitudes of prefabricated and cast-in-place reinforcement methods are different.The deformation amplitudes of walls reinforced with prefabricated ring beams and structural columns are relatively small,and the deformation hysteresis effect is more obvious.The seismic effect of the reinforcement measures of prefabricated ring beams and structural columns exceed the reinforcement methods of cast-in-place.
