【摘要】 作为结构抗震主要手段之一的TMD和TLCD技术,因具有良好的调谐特性而被广泛研究,但把两者结合起来进行振动控制的研究还较少。把此两种控制技术结合在一起可以有效地利用楼顶部的水箱而达到减轻TMD的质量。本文以TMD-TLCD混合控制为研究对象,在建筑物采用多自由度的前提下,详细推导了系统的振动方程。此外,还考虑到TLCD中含有非线性,本文采用了等价线性化原理进行了处理,并分析了其误差。最后,以12层建筑结构为实例,计算结果表明本文方法减震效果明显。更多还原

【Abstract】 As a primary means in structure anti-seismic fields,TMD and TLCD have been widely developed for their good tuning characteristics,yet the research on the combination of both seems scanty.To combine these two control technologies,the design mass of TMD can be effectively reduced,using the tank on the roof.The paper,with TMD-TLCD hybrid control as research subject,deduces the vibration equations when the building uses multi-degree freedom system,adopting the equivalence linearization principle owing to the presence of non-linearity in TLCD,and analyzes the corresponding errors.The method is proven capable of depressing the structural response with 12-story building as a case in point.更多还原
