【Abstract】 How to minimize the seismic damage is one of the most important research subject s in structure engineering. Structure vibration control would open a new route f or anti-seismic design of the engineering structures. As a passive control devi ce, Multiple Tuned Liquid Damper (MTLD) has its advantages of low cost, high rel iability, easy-to-operate and so on. Therefore, it is in researchers’ good gra ces. It is on this basis the function of MTLD on high-rise building has been fu rther studied. The formula of equivalent damping ratio of MTLD system of high-r ise structure building was derived. All parameters that contribute to the formul a of equivalent damping ratio are pointed out. Taking a tall building of 24 stor ies as an example, all parameters contributing to the equivalent damping ratio a re studied, and its design optimized obtaining good control efficiency.更多还原
