ABSTRACTSuppression of structural vibrations is an important design consideration for structuressubjected to dynamic excitations There are many methods to control the vibration ofstructures either in passive or in active ways Tuned Liquid Damper TLD is apassive control device that nowadays using of it increased because it is aneconomical and effective absorber A Tuned Liquid Damper TLD consists of a rigidtank partially filled with liquid and relies upon the liquid sloshing forces or momentsto dissipate vibrational energy and to suppress structural vibrations The result ofdamper becomes more effective by tuning the fundamental sloshing fluid frequency tothe natural frequency of the structure Some researchs have analysed Tuned LiquidDampers TLDs subjected to weak excitations so some effects such that turbulenceand wave breaking have been ignored But as the amplitude of excitation is increased the liquid responds violently such as occurrence of turbulence wave breaking Butimportant findings have been reported by some researchers who identified thatbreaking surface waves are a major mechanism of energy dissipation compared toliquid viscosity and container bottom roughness Also most of researches obtainresponse of structures subjected to 1 D excitations but the ground motions cause 3 Dmotions of building So this research focuses on modeling of liquid sloshing inrectangular tanks and considering wave breaking as a Tuned Liquid Damper TLD and effects of it in response of shear buildings equipped with TLDs subjected to 2 Dexcitations
