영어 초록
This paper proposes a tuned liquid column sloshing damper(TICSD) and its optimal design to mitigate bidirectional responses of building structures. The proposed damper acts as a liquid column vibration absorber (LCVA) and a tuned sloshing damper(TSD), respectively, in both principal axes of building structures. Optimum designs of the TLCSD addresses the minimizing in terms of live load, area and volume due to its installation, comparing to each installation with two dampers in two principal directions, respectively. Numerical results from optimum designs shows that the control robustness due to changes in the effective column length and the effective mass of the TLCSD superiors to that uses the head loss coefficient and damping nets in an existing liquid column vibration absorber(LCVA) and TSD. The TLCSD is designed according to the similarity laws of 76 story benchmark building model. Numerical model of the proposed TLCSD is derived based on the experimentally obtained transfer functions according to rotational angles.
