【摘要】 在振动台试验的基础上,进一步对受地震影响后的早龄期钢筋混凝土柱进行低周反复荷载下的拟静力试验,并与未受到地震影响的试件进行了对比。通过对试件的裂缝机理、P-Δ滞回及骨架曲线、耗能及承载能力等方面的计算分析,得到了早龄期受到不同程度损伤后的柱远期抗震性能。更多还原

【Abstract】 Based on the shaking table tests,it was done the static test of these columns under low cyclic loading,which were compared with specimens which were not affected by the earthquake.Through calculation and analysis of cracks mechanism,P-Δ hysteresis and the skeleton hysteresis curve,energy dissipation and carrying capacity etc,it was got the long-term performance of the early columns having different degrees of damages.更多还原
