为促进大跨空间结构隔震技术的发展,论文系统分析了目前常用的几类隔震支座,针对其中的一些问题,提出了一种新的三维复合隔震支座.该新型支座水平采用摩擦滑移隔震,竖向采用螺旋弹簧或碟形弹簧隔震.基于概念模型,设计制作了两类支座,对其动力特性进行了振动台试验研究,并依据试验结果建立了其理论模型.最后,对复合隔震支座在大跨空间结构中的隔震性能进行了模拟分析,结果表明该支座具有优良的隔震性能,能有效解决大跨空间结构的三维复合隔震问题.
In order to promote the development of the isolation technology of large-span space structures, the dissertation systematically analyzes several commonly used standoffs and proposes a new three-dimensional composite isolation standoff for some of these problems. The new standoff level Based on the conceptual model, two kinds of bearings were designed and manufactured, and the shaking table test of the dynamic characteristics was carried out. According to the test results, the theory was established Model.Finally, the seismic isolation performance of the composite isolation bearings in long-span space structures is simulated and the results show that the bearings have excellent isolation performance and can effectively solve the 3D composite isolation problem of long-span space structures .
