在低周反复循环荷载作用下钢筋混凝土框架梁端抗震性能的试验研究(3)

提供了整个24根钢筋混凝土框架梁端试件中的16根试件在低周反复荷载作用下的试验研究结果;论述了箍筋的受力性能以及横向配箍率和间距对梁端的破坏型态、位移延性、曲率延性、功比指数、吸收和耗散能量能力等的影响,并且指出了有效提高梁端抗震性能的最优配箍条件。

Experimental Investigation on Earthquake-Resistant Behavior of the Beam End of Reinforced Concrete Framed Structures Under Low Repeated and Reciprocal Loading (3)

This paper presents the experimental results of 16 specimens out of the whole 24 beam end specimens of reinforced concrete framed structures under low repeated and reciprocal loading;discusses the perforrnace of stirrup bearing force and the effect of web reinforcement ratio and distance between stirrup centers on the mode of failure,deflection ductility,curvature ductility,coefficient of work ratio and energy absorbing and dissipating capacity of,the beam end,and demonstrates the superior condition fo setting stirrup for well enhancing earthquake-resistant behavior of beam end.
