摘要:
为研究高强箍筋约束高强混凝土(HSC)柱弯曲破坏的荷载-位移全曲线,对10根HSC柱的低周反复加载试验结果进行研究,分析了轴压比、箍筋间距以及配箍率对其骨架曲线的影响,给出了HSC柱4个特征点——开裂点、屈服点、峰值点和极限点所对应荷载及位移的计算方法,建立了高强箍筋约束高强混凝土柱四折线荷载-位移骨架曲线简化模型.对比表明,本文提出的骨架曲线模型可以较好表达该类型柱弯曲破坏各特征点的趋势,其计算结果与试验结果拟合较好.
Abstract:
To study the load-displacement curve of high-strength concrete(HSC)columns confined by high-strength stirrups in flexural failure, low cyclic reversed loading tests were carried out on ten HSC columns with different design parameters. The effects of axial compression ratio, stirrup spacing, and stirrup ratio on skeleton curves of HSC columns were analyzed. Based on the test data analysis, the skeleton curve model for predicting the cracking, yielding, maxing and failure loads, as well as corresponding displacements, of HSC columns failed in flexure mode were developed. Then the four-linear skeleton curve model of HSC columns with flexure failure was established according to the four feature points. According to the comparison results, it's shown that the skeleton curve model proposed in this paper can better express the characteristic points of this type of column, and the calculated results fit well with the test results.
