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(1)

An Experimental Investigation on Earthquake-Resistant Behavior of the Beam End of Reinforced Concrete Framed Buildings under Low Repeated and Reversed Loading (1)

摘要: 本文是整个试验研究24个试件中的一组试件的试验研究的结果,通过9根钢筋混凝土梁试件在低周反复循环荷载作用下的试验,研究了框架梁端上面的不同配筋率μ_s,及其梁在下面和上面的不同配筋比值μ_x/μ_s对梁端抗震性能的影响。

Abstract: This paper presents the experiment results of 9 reinforced concrete specimens which form a set out of the whole 24 specimens. All these 9 specimens were tested under low repeated and reversed loading to investigate the effect of the beam end top steel ratio μ_s and various bottom versus top steel ratio(μ_x)/(μ_s) on the earthquake resistant behavior of the beam end.
