【摘要】 液柱式阻尼器(LCVA)的U型管的横截面积非均匀,其自振频率不仅取决于液柱长度,还取决于其几何形状,从而比液体阻尼器(TLCD)具有更大优越性,本文研究了新型的被动调谐减震装置LCVA在地震作用下的优化参数,提出了求最优均方反应的直接法,比TLCD文献中所用的叠代法更为简捷有效.更多还原

【Abstract】 Studies the optimum absorber parameters of Liquid Column Vibration Absorber(LCVA),which is a new type of passive tuned liquid damper developing on the base of Tuned Liquid Column Damper(TLCD),and has an crosssection of nonuniform, It’s natural frequency is determined not only by the length of the liquid column, but also the geometric configuration . So the LCVA provide more architectural adaptability than TLCD.更多还原
