Abstract
In order to study the seismic performance of reinforced concrete-sintered wall panel composite frame structures,thefailure patterns,hysteresis curves,skeleton curves,stiffness degradation and energy dissipation characteristics of the frame structures were systematically analyzed through low-cycle repeated loading tests.The results show that there is no obvious crack in the initial loading stage.With the increase of displacement,cracks appear and expand in the beams,columns and wall panels,and some wall panels break and fall off.With the increase of displacement,the load of the specimen first increases linearly,then increases slowly and then decreases.Secant stiffness decreases rapidly at first and then slowly.The cumulative energy consumption rose slowly first and then rapidly.When the horizontal displacement is 20 mm,the secant stiffness of the second cycle is 9%lower than that of the first cycle.In the first cycle,the energy consumption increased by 157%when the horizontal displacement increased from 5.86 mm to 59.25 mm;When the horizontal displacement is 100 mm,the energy consumption increases by 323%compared with 59.25 mm.关键词
