THE SEISMIC BEHAVIORS OF RECYCLED AGGREGATES CONCRETE HOLLOW BLOCK WALLS

Under different vertical loads，the low-cycle reversed loading test of 3 pieces of recycled aggregate concrete hollow block walls ＲACHBW specimens with 85% recycled coarse aggregate’s replacement ratio was conducted in this research． The load carrying capacity，damage process，failure characteristics of ＲACHBW were studied ，and also the seismic behaviors，such as hysteretic characteristics，skeleton curve，ductility and ability of energy dissipation，were analyzed． The research result indicates that in the damage process of the low-cycle reversed load， ＲACHBW specimens are similar with natural concrete hollow block walls NCHBW specimens． and that the ＲACHBW specimens has plump hysteresis curves， good ductility， strong energy dissipation capacity and good seismic performance． The conclusion is that this material can be used in real engineering structure．
