摘要研究了一种简单、低成本的摩擦基础隔震系统在降低农村建筑地震易损性方面的适用性。研究了大理石-大理石、大理石-高密度聚乙烯、大理石-橡胶板和大理石-土工合成材料四种摩擦隔震界面。这些接口的摩擦性能进行了研究，在静态和动态条件下的正常负载范围从10到50 kN。除大理石-橡胶外，所有这些界面的平均摩擦系数均在0.05-0.15的范围内。这些隔离系统的有效性进行了研究分析和实验的频谱兼容的地面运动对应的最大可信地震的最严重的地震区，根据印度的抗震设计标准。分析预测的建筑物的地震反应与这样的隔离被认为是在良好的协议（19%以内）与实验观察。这是...
AbstractA simple low-cost friction base-isolation system is examined for its applicability in reducing seismic vulnerability of rural buildings. Four friction isolation interfaces, namely, marble–marble, marble–high-density polyethylene, marble–rubber sheet, and marble–geosynthetic, were studied. The friction properties of these interfaces were studied under static and dynamic conditions for a range of normal loads from 10 to 50 kN. The average coefficients of friction for all of these interfaces except marble–rubber were found to be in the range of 0.05–0.15. The effectiveness of these isolation systems was investigated both analytically and experimentally for a spectrum-compatible ground motion corresponding to the maximum credible earthquake for the most severe earthquake zone according to Indian standards for earthquake-resistant design. The analytical prediction of seismic response of buildings with such isolation was found to be in good agreement (within 19%) with the experimental observation. It wa...
