密肋壁板轻框结构隔震房屋模型振动台试验分析

ANALYSIS OF THE SHAKING TABLE TEST OF THE ISOLATED HOUSE OF MULTI-RIB SLAB WITH LIGHT-WEIGHT OUTER FRAME STRUCTURE

通过对密肋壁板轻框结构隔震房屋与非隔震房屋模型振动台的试验 ,就隔震房屋的设计、减震效果、振动特性及地震反应进行了分析探讨。试验结果表明 ,自阻尼叠层橡胶隔震系统性能稳定 ,隔震效果显著 ,只要进行合理的隔震设计 ,隔震房屋的地震反应较非隔震房屋的地震反应可降低 2

Based on the shaking table test of an isolated model house and a non-isolated model house of multi-rib slab with light-weight outer frame structure,the design and effect of earthquake disaster mitigation and vibration properties and seismic response of an isolated model house are also analysed. It can be seen from the results of the experiment, the system of self-damping-steel-plate-laminated-rubber-bearing-isolation is stable in properties and effective in isolation. The seismic response of the isolated model house can be reduced by about 2/3 as compared with the non-isolated model house on the base of reasonable isolation design.
