不同加载方式下波形钢板-橡胶黏弹性阻尼器力学性能试验研究
Experimental study on mechanical properties of corrugated steel plate-rubber viscoelastic dampers under different loading methods
摘要
Abstract
The use of energy dissipation devices such as dampers can significantly enhance the seismic perfor-mance of building structures,compensating for the shortcomings of traditional seismic design methods.In this study,four corrugated steel plate-rubber viscoelastic damper specimens with identical specifications were de-signed.Deformation tests,conventional mechanical tests,and fatigue performance tests were conducted,fo-cusing on the correlation between the interfacial bonding mechanism and the overall performance of the damp-ers,as well as the variation patterns of their mechanical performance indices under different loading modes.The results show that cumulative interfacial damage is the primary cause of damper performance degradation,and its evolution process can be divided into four stages:undamaged,initial damage,damage propagation,and failure.The hysteresis curves of the dampers are smooth and symmetric,exhibiting stable hysteretic be-havior,where the continuous deviation of the loading and unloading paths is strongly correlated with interfa-cial damage accumulation.The mechanical performance indices present clear regularities with respect to shear displacement,number of cycles,and loading frequency.Under large-displacement loading,the dampers ex-hibit high load-bearing capacity and energy dissipation ability,with a maximum damping force of 151.93 kN.In fatigue tests,the equivalent damping ratio and loss factor show a slow increasing trend,and the dampers maintain high fatigue energy dissipation capacity.关键词
