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。
The energy dissipation technology and base isolation technology were applied to the structure of Chengjiang Fossil Museum, and the simulated shaking table test was carried out on the 1/30 scale model of the complex steel structure in the high intensity region. The dynamic characteristics and seismic response of the structure are studied. The BRB is analyzed, the energy equation is deduced, the energy input to the structure, the energy dissipation of the isolation layer and the energy consumption of the superstructure are analyzed based on the energy principle. Its energy consumption distribution. The analysis results show that the seismic isolation energy consumption accounts for about 90% of the seismic input energy, and the damping effect is very obvious.
