对核筒悬挂建筑减振体系主结构的抗侧性能进行了分析,结果表明:在倾覆力矩没有明显增加的前提下,考虑与箱基础倾斜耦合作用的主结构侧向位移比不考虑耦合作用的可能大1倍以上;当悬挂建筑结构的基准频率ω1不变时,其侧向振动幅值受上部结构阻尼比ξ1和激励频率比β的影响显著;推导出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,其中,在9度区高宽比限值比较小,因此不适合建造单核筒式悬挂建筑,但可以选择巨型框架式等其他形式。
The anti-side performance of the main structure of the vibration-damping system of the core-tube suspension structure is analyzed. The results show that under the condition of no obvious increase of overturning moment, considering the lateral displacement ratio of the main structure which is inclined to the box foundation, The amplitude of lateral vibration is significantly affected by the damping ratio ξ1 and the excitation frequency ratio β of the superstructure when the reference frequency ω1 of the suspended structure is constant. Structure at different seismic fortification intensity of the nominal aspect ratio limits, of which the aspect ratio of 9 degrees area is relatively small, it is not suitable for the construction of single-core tubular suspension structure, but you can choose other forms such as giant frame.
