|
摘要
根据碳纤维布加固燕尾榫柱架低周反复荷载试验结果,提出了往复荷载作用下碳纤维布加固燕尾榫柱架的特征参数计算公式,研究其二阶效应、卸载刚度变化规律及滞回规则,建立并提出了能够反映碳纤维布加固燕尾榫柱架地震作用下真实受力状况的荷载-位移恢复力特征曲线,并与试验结果进行对比,该曲线拟合效果较好,表明本文提出的碳纤维布加固燕尾榫柱架恢复力特征曲线具有一定的适用性.
Based on the results derived from low cyclic reversed loading of dovetail column-frame strengthened with CFRP,the formula of the characteristic coefficient was proposed,second order effect,regularity of unloading stiffness degeneration,hysteresis rules were especially investigated,and the load-displacement restoring force characteristic curve of dovetail column-frame strengthened with CFRP which indicated its real stress state under the action of earthquake have been set up.Compared with experiments results,the load-displacement restoring force characteristic curve fits better and it is found that the restoring force characteristic curve is of certain degree of adaptability.
