Experimental Study on Seismic Behavior of Recycled Concrete Latticed Wall

摘要

The low cycle loading tests of 3 pieces of recycled concrete latticed walls under different side column reinforcements and different axial pressure ratios are conducted.The failure mode,failure process,hysteresis curve,ductility,and energy dissipation of the walls are studied.The experiment results indicate that the failure mode of recycled concrete latticed wall under the cyclic load is shearing failure.It can enhance the ductility of the wall,distortion ability,and the earthquake resistance performance,with increasing the axial load ratio.It can enhance the ultimate load and restrain the crack development by increasing the reinforcement of the side columns.
