摘要
采用正交试验的方法,以能量法为基础,以滑移隔震结构的阻尼耗能为反应指标,分别探讨在Ⅱ、Ⅲ、Ⅳ类场地条件下,滑移隔震结构相关参数对结构阻尼耗能的影响趋势,并对其敏感性做相应的分析。研究表明:滑移隔震结构的阻尼耗能对摩擦系数和上部结构的固有周期均较为敏感,而对质量比均较为不敏感,上部结构的阻尼耗能与隔震层的阻尼耗能对其他参数的敏感性较为不同,参数的敏感性次序可能会不一致。
Using orthogonal test method,based on energy method and taking the damping energy dissipation of sliding base-isolated structure as the response index,it was explored the effect under the Ⅱ,Ⅲ,and Ⅳ sites conditions of the associated parameters of sliding base-isolated structure on damping energy dissipation of structure and their sensitivities were analyzed. It was found that the damping energy dissipation of sliding base-isolated structure was more sensitive to the friction coefficient and the natural period of superstructure,and was insensitive to the mass ratio. The sensitivities of the damping energy dissipation of superstructure and isolation layer to the other parameters were more different,and the sensitivity sequence of parameters might be inconsistent.
