进行了16个栓钉连接件试件在重复荷载作用下的滞回性能实验研究,考察横向配筋率和栓钉间距对栓钉力学性能的影响。结果表明:栓钉连接件的滞回曲线较为饱满,耗能能力强;当横向配筋率在0.4%~0.79%之间时,试件的延性和耗能能力都得到明显的提高;继续增加到1%时,试件的延性开始下降,但耗能能力继续增加;同样,当栓钉间距在40~80mm之间时,试件的延性得到提高,而耗能能力下降;当栓钉间距在80~160 mm之间时,试件的延性开始降低,但是,耗能能力提高。
Sixteen specimens of stud connector were experimentally studied on the hysteretic behavior under repeated load.The horizontal reinforcement ratio and the stud pitch were considered as the experimental parameters of their seismic behavior.The results indicate that the stud connector has plump hysteretic loops,stronger energydissipation capacity;The horizontal reinforcement ratio is 0.4%-0.79%,the ductiblity and the energy dissipation capacity is improved obviously,as the horizontal reinforcement ratio is 1%,the ductiblity of the specimen is dropped and the energy dissipation capacity is still improved;As the stud pitch is between 40 mm and 80 mm,the ductiblity of the specimen is improved but the energy dissipation capacity is reduced obviously,as the stud pitch is between 80 mm and 160 mm,the ductiblity of the specimen is dropped but the energy dissipation capacity is improved.
