Abstract

This paper focus on the seismic response control of eccentric structures using tuned liquid column dampers (TLCD) and circular tuned liquid column dampers (CTLCD). An 8-story eccentric steel building, with two TLCDs on the orthogonal direction and one CTLCD on the mass center of the top story, is analyzed. The optimal parameters of liquid dampers are optimized by Genetic Algorithm. The structural response with and without liquid dampers under bi-directional earthquakes are calculated. The results show that the torsionally coupled response of structures can be effectively suppressed by use of liquid dampers with optimal parameters.
