Abstract

Here, in order to solve problems of insufficient aseismic capacity and difficult to repair after earthquake damage of prefabricated frame joints and connections, a new type of prefabricated energy dissipation joint connection was proposed. Low-cycle repeated loading tests were conducted for its key energy dissipation component called the replaceable weakened restrained steel-plate damper to investigate its hysteretic performances of load-bearing capacity, energy dissipation capacity, stiffness degradation and ductility, reveal its failure mechanism, and analyze effects of slot-opened weakening form, weakening length, steel plate thickness and gap between restraint sleeve and weakened steel plate on mechanical properties of the damper. The results showed that the replaceable weakened restrained steel plate damper cracks or breaks at the position of weakened section to realize controllable plastic energy dissipation and damper failure mode, and have good dual-function of load-bearing and energy dissipation; under the same parameters, load-bearing capacity, energy dissipation capacity and ductility of dog bone weakened restrained steel plate damper are better than those of vertical slot-opened weakened restrained steel plate damper; weakening length has a larger effect on ductility and lateral buckling performance of steel plate, steel plate thickness has a larger effect on load-bearing capacity and stiffness degradation performance; when gap between restraint sleeve and steel plate is larger, restraint sleeve can’t have effective action to cause the compression buckling of weakened steel plate.
