Experimental study on mechanical behavior of sinusoidal waveform steel plate damper
In order to solve the problems of low out-of-plane stiffness of the energy dissipation web of traditional shear plate damper and easy to occur out-of-plane buckling under large deformation,a sinusoidal waveform steel plate damper was proposed.Considering the placement direction of the waveform web and the yield strength,four specimens were designed and tested under low cycle repetitive load to analyze the hysteretic performance,bearing capacity and stiffness degradation.The results show that strong energy dissipation capacity,good ductility,and stable hysteresis performance under large deformation is the characteristics of sinusoidal wave plate damper,and the transverse wave steel plate damper with low peak load is the best.The energy dissipation capacity and ductility are better than those of the vertical waveform steel plate damper,and its stiffness degradation rate is higher than that of the transverse waveform steel plate damper.The hysteretic curve of webs made of low yield point steel is full.
