复合隔震结构高宽比限值研究
|
摘要
复合隔震结构是将夹层橡胶支座与摩擦滑移支座并联组合在一起作为隔震层的基础隔震结构。文中对复合隔震结构的高宽比限值进行了研究,推导出了简化的计算公式。同时分析了摩擦系数、摩擦滑移支座承载系数、地震动强度、地震波特性等因素对结构高宽比限值的影响及其规律,得出了一些有益的结论,为复合隔震结构的设计提供了一些参考。
A composite isolation structure is combined by laminated rubber bearings and sliding isolation bearings.Study on limit values of height-to-width ratios for the composite isolation structure is presented.The simplified formulation has been derived for the structure,and some influencing factors,such as friction coefficient,friction sliding isolator bearing ratio,seismic intensity and seismic wave characteristics,have been discussed.The results above can provide references to the design of composite isolation structures.
