【摘要】 组合隔震结构体系中,当基础隔震体上部结构层间刚度相对较小、垂直荷载较大,且其采用的叠层橡胶垫的橡胶总厚度较大时,隔震支座不仅会产生水平变形,同时也会产生竖向变形,导致上部结构产生摆动,而这种摆动可能对隔震体本身及联接体的振动控制产生影响。推导了组合隔震结构考虑摆动的振动及控制方程,分析研究了摆动对组合隔震结构的振动控制影响。研究结构表明:在组合隔震体系中,隔震体的摆动对隔震体本身及联接体的振动控制都有一定的影响。更多还原

【Abstract】 The multi-story packing rubbers in combined isolation structure system may cause the upper layers of the isolated structure to produce swing motion, which will influence the vibration-control of isolated structures and their combined structure . The vibration control equation of a combination of isolated structures was derived in consideration of the swing motion and the swing’s influences on its vibration-control were analysed.更多还原
