灌孔混凝土砌块砌体受压性能研究
|
摘要
通过对灌孔混凝土砌块砌体中混凝土芯柱三向受压应力状态进行分析,提出了适用于灌孔混凝土受压弹性模量的计算方法.同时,基于大量的试验结果,提出了适用于灌孔混凝土砌块砌体的泊松比、峰值应变、极限应变等参数,并引入到Domingo J.Carreira等提出的混凝土本构模型中,得出了适用于灌孔混凝土砌块砌体受压的应力-应变全曲线公式.对比结果表明,计算值与试验结果吻合良好,可供灌孔混凝土砌块砌体结构设计和研究参考.
Three axial compressive stresses of concrete core column in grouted concrete masonry were studied.The method of elastic modulus for grouted concrete masonry was presented.Based on lots of grouted concrete masonry tests,the formulas of poisson's ratio,peak strain,and ultimate strain for grouted concrete masonry were presented.These parameters and Domingo J.Carreira's construction model for concrete were used to determine the stress-strain curve for grouted concrete masonry.The results obtained by the formulas agreed well with the experimental results,which provided a reference for grouted concrete masonry design and research.
