［摘要］将消能减震技术与基础隔震技术联合应用于澄江化石博物馆结构中，并对该高烈度区复杂钢结构进行了1/30比例模型的模拟振动台试验。研究了该结构的动力特性和地震响应等问题，分析了BRB，推导了能量方程，应用能量原理对该结构的地震输入能、隔震层耗能和上部结构耗能进行了分析，给出了其耗能分布关系。分析结果表明，隔震层耗能占地震输入能的90%左右，减震效果十分明显。

Abstract:The energy dissipation technology combined with the base isolation technology were applied in the structure of Chengjiang Fossil Museum. A shaking table test on a 1/30 scaled model of an irregular steel structure in high seismic fortification intensity site was conducted. The dynamic characteristics and seismic response of the structure were studied, and the BRB was analyzed and  the energy equation was  deduced. The energy principle was used to analyze earthquake input energy of the structure, energy dissipation of isolation layer and energy dissipation of superstructure, and the energy distribution relationship was provided. The analysis results show that the energy dissipation of isolation layer accounts for about 90 percent of earthquake input energy, which proves that the base isolation system effects are very well.

Keywords:Chengjiang Fossil Museum; isolated structure; energy dissipation；shaking table test; energy analysis; high seismic fortification intensity site
