【Abstract】 Research and practice show that enhancing the strength,ductility and dissipation capacity of the structure by using steel reinforced lightweight aggregate concrete is an effective way to improve the seismic resistance.Lightweight aggregate concrete(LAC) has dual features of light weight and high strength.Furthermore,the elastic modulus of LAC is smaller,dead load of the structures made with LAC is smaller;seismic wave spreads slower in it,natural vibration period is longer,so the structure can absorb the impact energy quickly.更多还原
