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(2)

An Experimental Investigation on Earthquake-Resistant Behavior of the Beam End of Reinfored Concrete Framed Structures under Low Repeated and Reciprocal Loading(2)

摘要: 本文对24根梁端试件中的6根钢筋混凝土梁试件在低周反复循环荷载作用下的试验,研究了梁端不同的剪跨比a/h₀对梁端抗震性能的影响。结果表明,剪跨比a/h₀对梁端的破坏形态、位移延性、曲率延性、吸收和耗散能量的能力都起着决定性的影响。

Abstract: This paper reports the test results of 6 reinforced concrete beam end specmens out of 24 specimens under low repeated reciprocal loading. The effect of different shear span ratios of the beam end on its earth- quake resistant behavior is investigated. The test results show that the shear Span vatio of the beam end has a critical effect on the mode of failure, deflection ductility, curvature ductility, and energy absorbing and dissipating capacity of the beam end.
