摘要
提出一种二硫化钼固体润滑剂涂层的新型分离式摩擦滑移隔震装置,为研究该新型隔震系统对结构抗震性能的影响,进行了隔震和非隔震结构的模型振动台对比试验。基于试验结果,从结构的动力特性、位移反应及加速度反应等方面评价结构抗震性能,并对比分析了该新型摩擦滑移隔震系统的隔震效果。研究表明:二硫化钼固体润滑剂涂层具有较高的竖向承载特性和低摩擦特性,新型分离式摩擦滑移隔震系统能够有效降低结构地震响应。相比于非隔震结构,采用新型分离式摩擦滑移系统的隔震结构的楼层加速度、层间位移角均减小,地震作用下,结构能量的耗散主要集中在隔震支座处,该隔震系统具有良好的隔震效果,结构可以满足抗震要求。
A seismic isolation with innovative separated friction sliding device used molybdenum disulfide lubricant coating has been proposed. In order to study the effect of this system on seismic behavior of structure,the comparison tests of shaking table in the isolated and non-isolated structure models were given. Based on the test results,the seismic behavior of the seismic isolation with innovative separated friction sliding device was evaluated in terms of dynamic characteristics,displacement response and acceleration response,and isolating affection was compared and analyzed. Test result reveals that molybdenum disulfide lubricant coating has better vertical bearing capacity and lower friction,the seismic isolation with innovative separated friction sliding device can reduce the seismic response of structure efficiently. Compared with non-isolated structure models,the floor acceleration and story drift angle of isolated structure adopting innovative separated friction sliding device decreased. Under seismic action,the scope of the energy dissipation concentrates at isolation bearing,this seismic isolation has better isolating affection and the isolated structure satisfies design requirement.
