本文通过20根试件的实验结果,讨论了钢筋陶粒混凝土压弯构件在周期反复荷载作用下的滞回特性及延性,研究了轴压比,箍率及纵向配筋率等因素对构件滞回特性及廷性性能的影响。在实验的基础上,对构件的廷性进行了分析,归纳出构件位移廷性比的经验公式。并将钢筋陶粒混凝土的构件性能,与普通钢筋混凝土构件的性能作了对比,对比结果说明,影响延性的因素基本相同。文中还对节点区钢筋的粘结滑移进行了实测。最后利用电子计算机,对弯矩——曲率滞回曲线作了理论分析,并与实验结果进行了对比,对比结果表明,两者比较接近。
In this paper, through the experimental results of 20 specimens, the hysteresis characteristics and ductility of reinforced concrete ceramic concrete under bending and bending are discussed. The factors such as axial compression ratio, hoop rate and longitudinal reinforcement ratio are studied. Back to the impact of properties and properties. Based on the experiments, the tactility of the components was analyzed, and the empirical formula of the component displacement ratio was concluded. The performance of reinforced ceramsite concrete is compared with the performance of ordinary reinforced concrete members. The comparison results show that the factors affecting ductility are basically the same. In this paper, the bond slippage of the rebar in the joint zone is also measured. Finally, using computer, the theoretical analysis of the bending moment-curvature hysteresis curve was made and compared with the experimental results. The comparison results show that the two are close.
