摘要
为了提高现浇梁和叠合板的连接性能与施工质量,得出性能较好的现浇梁-叠合板连接方式,优化构件的承载能力,开展了4种连接类型现浇梁-叠合板构件的加载试验,对比了各试件的延性、承载能力、刚度退化,研究结果表明:试件连接方式为斜插筋时的变形延性、承载能力、刚度退化性能均超过出筋连接;对于不同连接方式的试样,正向承载力最大的为叠合面搭接;与斜插筋和出筋连接方式相比,试件连接方式为凹槽钢筋连接时的延性、承载能力较好,反向刚度比退化速度较慢,滞回性能较好。
In order to improve the connection performance and construction quality of cast-in-place beams and composite slabs,obtain a better connection method of cast-in-place beams and composite slabs,and optimize the bearing capacity of the components,load tests were conducted on four types of connection types of cast-in-place beams and composite slabs.The ductility,bearing capacity,and stiffness degradation of each specimen were compared.The research results showed that the deformation ductility,bearing capacity,and the degradation performance of stiffness exceeds that of reinforced connections.For specimens with different connection methods,the maximum forward bearing capacity is the overlap of the overlapping surfaces.Compared with the diagonal joint reinforcement and outlet reinforcement connection methods,the specimen connection method with groove reinforcement has better ductility and load-bearing capacity,slower degradation rate of reverse stiffness ratio,and better hysteresis performance.
