【摘要】 对一单轴对称框架结构,通过刚接、铰接以及连接体位置2种不同的隔震消能部件设置方式共4种连接方案,采用快速非线性分析方法(FNA),沿结构X、Y方向输入EI-Centro波,研究连体框架结构在连接方式变化时,结构抗震性能的变化。计算结果表明:连接体位置引入隔震消能部件能大幅减小结构在地震作用下的地震响应,提高结构的抗震性能。其中在连接体端部设置双向橡胶隔震支座与阻尼器的"柔性"连接,效果尤为显著。更多还原

【Abstract】 Aseismic performance of a monosymmetrical double-frame structure is studied by the method of fast non-linear analysis(FNA) when the four types of connection patterns are changed.The results show that,the using of energy-consuming devices can significantly reduce the seismic response of structures under seismic action and improve the seismic performance of the monosymmetrical connected double-tower structure.The effect of setting the isolations and dampers at the end of the connection is more particularly significant than setting the isolations and dampers at the connection inside.更多还原
