摘要
为充分利用结构物内部储水装置的经济性及实用性,调谐类阻尼器有更多样的设计。提出了调谐混合水箱/质量阻尼器(THMD)的概念。分析了由调谐液柱阻尼器(TLCD)与调谐液体阻尼器(TLD)组合而成的混合水箱内水的动力效应对THMD系统控制性能的影响;并提出运用最优动力方法对THMD进行设置。算例分析表明,THMD可取得与TMD相当,优于TLD、TLCD的控制效果;而运用最优动力方法设置的THMD的控制性能明显优于普通方法,并为适应结构物内部使用空间要求提供了更为宽松的条件。
In order to make full use of the economical and practical properties of storage water equipment inside structure and show diverse designs for tunedtype damper systems,a new tuned-type damper-tuned hybrid-tanks/mass damper (THMD) was presented.The influence of dynamic effect of the hybrid-tanks composed of TLCD and TLD on the controlling performance of the THMD system was analyzed,and the optimum dynamic method was proposed to set the THMD.Numerical results show that THMD set can achieve an effect close to that of an ordinary TMD,while outperforming TLD and TLCD,that the controlling performance of THMD set by the optimum dynamic method is much better than that set by the general methods,and that the design of THMD dimension set by the optimum dynamic method is more reasonable for using the structural inner space.
