摘　　要：通过对1根玄武岩复材筋珊瑚骨料混凝土梁、1根碳纤维复材筋珊瑚骨料混凝土梁和2根碳纤维复材筋普通混凝土梁的受弯试验,探讨不同纵筋、箍筋以及混凝土种类和强度下的梁破坏形态;得到了各种不同工况对复材筋珊瑚骨料混凝土梁和普通混凝土受弯梁开裂荷载、极限承载力和挠度的影响规律;验证了现有计算方法对复材筋珊瑚骨料混凝土梁和普通混凝土梁受弯的适用性。By tests on one coral aggregate concrete beam with BFRP bars,one coral aggregate concrete beam with CFRP bars and two concrete beams with CFRP bars,it was investigated the failure modes of the beams with different beam longitudinal reinforcement, stirrup, concrete types and intensities. The influences of different working conditions on the cracking load,ultimate bearing capacity and deflection of the coral aggregate concrete beams with FRP bars were obtained,which verified the applicability of the existing calculation methods of the（ coral aggregate）concrete beams with FRP bars.
