【摘要】 地震是突发性的自然灾害 ,目前人们尚不能对地震做出很好的预测。不同烈度地震作用要求铅芯橡胶隔震支座具有不同的性能 ,研究其在多遇地震及罕遇地震作用下的反应性能具有重要的意义和价值。本文进行了铅芯橡胶隔震房屋模型振动台试验研究 ,分别对模型结构输入了不同烈度的地震波 ,并对试验结果做了分析比较 ,结果表明本文设计的铅芯橡胶支座在大震和小震时均具有良好的性能更多还原

【Abstract】 Earthquake is of randomness and can not be predicted so far. It is very important to investigate the characteristics of buildings with lead rubber bearing under multi-intensity ground motion. In this paper, shaking table tests were conducted in order to check the characteristics as above and experimental results were compared. The results prove that the model building in the paper performes very well not only under lower intensity ground motion but also under strong ground motion.更多还原
