摘　　要：通过对狗骨式刚性连接钢框架在低周往复荷载作用下的试验,研究了该类型结构的破坏形态、变形特点、荷载-位移滞回曲线、结构耗能性能等,分析了狗骨式刚性连接钢框架的受力特点及抗震性能.同时对狗骨式刚性连接钢框架进行了有限元分析,其结果与试验吻合较好.进一步说明通过合理的设计狗骨截面,能使其对框架的抗震性能起到保险丝的作用.Through experiment with the dog-bone connection steel frame under low reversed cyclic loading, several characteristics of such frame behaviors, such as failure features, deformation and energy dissipation ability are studied. Seismic behavior of such steel frame is also analysed. At the same time , a finite element analysis method was adopted,The calculation results are in good agreement with those of the tests. It proves that through proper design the section of the dogbone, the sort of connecting form can act as a fuse for the seismic resistance of the steel frame. A reference basis is provided for the application of such frames.
