摘要:
针对强地震作用下隔震结构隔震层变形过大的现象提出了曲面隔震结构体系,该结构隔震层为曲面布置,在地震和结构重力作用下,上部结构可绕曲率中心进行曲面运动。建立了非平整曲面隔震结构多质点计算分析模型,通过数值分析进一步研究非平整曲面隔震层的曲率半径对结构地震响应的影响规律。分析结果表明:在罕遇地震作用下,曲面隔震结构对隔震层及上部结构的位移控制效果显著,同时当曲率半径为10~15倍重心高度时具有良好的隔震效果。
Abstract:
A curved-surface isolated structural system is proposed to deal with the large deformation of the isolation layer of the isolation structure under strong earthquake,in which the isolation layer is an uneven curved-surface.In the curved-surface isolated building,the superstructure is able to pivot freely around the center of curvature under the earthquake and structural gravity.A multi-degree-of-freedom dynamic model of the curved-surface isolated system is proposed,and the influence of the curvature radius of uneven curved-surface isolation layer on seismic response of the structure is further studied by the numerical analysis.The results are as follows.The displacements of isolation layer and superstructure in the curved-surface isolated structure can be effectively controlled under a rare earthquake.And the system has good isolation effect when the curvature radius is 10~15 times the height of the center of gravity.
