结构物的储水装置可被设计成调谐液柱/质量阻尼器(TLCMD),然而水柱由于晃动而产生的动力效应对整个调谐阻尼系统的结构控制效果有影响.鉴于此,提出用相位差分析的方法,同时考虑调谐液柱阻尼器(TLCD)与调谐质量阻尼器(TMD)共同作用的TLCMD系统的综合控制效应.通过数值模拟研究了不同水柱设计值的TLCMD系统在风振与地震激励下对结构的控制性能,对比了相应TMD、TLCD的控制效果,并对TLCMD的设置提出了建议.结果表明,TLCMD经优化设计后可取得与普通TMD相近的控制效果,优于TLCD.同时,TLCMD较TMD更经济,且更具实用价值.

Storage water equipment with the water weight can be designed to be a tuned liquid column/mass damper(TLCMD),however,the dynamic effect of water column affects the performance of the whole tuned damper system.In view of this,a phasic difference analysis method is presentes,considering synthetical effect of both the tuned liquid columm damper(TLCD) and tuned mass damer(TMD) in TLCMD system simultaneously,and through numerical simulation comparison of performance of ordinary TMD,TLCD and TLCMD in made under wind and earthquake excitation,respectively.Suggestions for designing a TLCMD are also provided.Results show that the optimally designed TLCMD can achieve a performance level close th that of and ordinary TMD,and outperforms TLCD.As compared with ordinary TMD,the TLCMD is more economical and practical.
