铅芯橡胶支座隔震钢框架结构体系振动台模型试验研究
|
摘要
设计并完成了铅芯橡胶支座隔震钢框架结构体系的振动台模型试验,研究刚性地基上隔震结构体系的动力特性和隔震效果,为进一步开展考虑土-结构相互作用的隔震结构体系振动台模型试验提供数据对比。试验结果表明:刚性地基上隔震结构体系具有良好的隔震性能,隔震效果显著,输入地震动的频谱特性和加速度峰值对隔震结构的隔震效率影响较大。
Shaking table tests on the model of a steel-framed structure system with lead core rubber bearing isolations have been designed and carried out,dynamic characteristics and isolated effects of the isolation structure system on rigid base are studied,numerical results will be taken as the comparison data for the shaking table tests of seismic isolation structure system considering soil-structure interaction.The test results show that the seismic isolation structure system on the rigid base has good isolated performance,the seismic isolation structure is very effective,and peak value and frequency spectrum of inputted earthquake motion have important influences on the isolated effects of the seismic isolation structure.
