【Abstract】 Seven beams which encased in steel hoops and grouted in different materials with low cycle repeatedly load are experimented.Then the different failure characteristic and bearing capacity of members are analyzed and the energy consumption by the energy method which be used to evaluate the members antiseismic capability is analyzed.At last the value of strength reducing coefficient( a s) is verified.According to the experiment,it is considered that the composite grout material can replace epoxy resin and whether grouted in or not can influence the result of reinforce.更多还原
