【摘要】 从浮顶参与地震响应的角度出发,采用Nagarajaiah模型模拟铅芯橡胶支座(LRB)的力-变形非线性行为,研究了铅芯橡胶支座隔震储罐的地震响应特征。分析了地震烈度、高径比以及场地条件对立式钢制浮顶储罐隔震与非隔震状态地震响应的影响。分析表明,不同工况下,隔震体系能够有效地降低储罐的倾覆力矩,减少基底剪力,满足结构控制。但对波高的控制效果并不明显。合理优化高径比,选择场地,可以得到理想的减震效果。
【英文摘要】 Starting in the perspective of the floating roof taking part in dynamic response,the Nagarajaiah model being adopted to simulate the non-linear hysteretic characteristics of force-displacement relationship for LRB and the seismic response of it have been analyzed.An analysis that the influence of seismic intensity,high aspect ratio and site conditions on the vertical steel floating roof storage tank with non-isolated and isolation have been done.The result indicates that the isolation system can effectively...
