对采用粘滞流体阻尼器和共享调谐质量阻尼器连接的带裙房不对称双塔楼结构连接控制方案进行了比较研究。采用在双体单自由度结构间Maxwell型阻尼器的最优参数表达式,并基于等效双体单自由度体系求得了双塔楼间粘滞流体阻尼器优化零频率阻尼系数与松弛时间,与通过大量数值计算得到的参数化结果吻合良好。并将优化设计后的阻尼器连接控制方案与共享调谐质量阻尼器控制方案进行了详细比较,数值比较结果表明二者控制效果相当,但是前者更具优越性。
A comparative study on the control scheme of unsymmetrical twin towers with podium connected by a viscous fluid damper and a shared tuned mass damper was carried out. Based on the optimal parametric expression of Maxwell-type dampers between two-body single-degree-of-freedom structure and the optimization of zero-frequency damping coefficient and relaxation time of twin-tower viscous fluid damper based on equivalent double-body single-degree-of-freedom system, The parameterized results obtained through a large number of numerical calculations are in good agreement. A detailed comparison of the damper control scheme with that of the shared tuned mass damper is carried out. The numerical results show that the two control schemes have similar control effects, but the former has more superiority.
