新型悬挂减振体系三个问题的概念分析
Journal Title: Science Paper Online - Year 2007, Vol 2, Issue 9
Abstract
本文针对新型悬挂减振体系的三个问题进行了概念分析；研究了P-Δ效应下核筒侧移与箱基础倾斜的静力耦合关系，根据静力分析，考虑耦合的主结构侧向位移比不考虑耦合的可能会大得多，而倾覆力矩却没有明显增加。本文还分析悬挂次结构刚体的摆动问题，表明刚体动力分析方法比质点动力分析方法更加接近于真实；且若要使得悬挂减振体系的主、次结构的动力响应都达到优化要求，则地震波的衰减系数既不能太大，也不能太小。根据现行规范，分别得到了正六边形核筒悬挂建筑主结构在不同抗震设防烈度时的名义高宽比限值。
