摘要:
随着建筑结构高度的增加,建筑构件的尺寸也越来越大,对大尺度梁柱节点抗剪承载力的准确预测是对高层建筑结构抗震安全性的重要保证,而通过试验研究发现,利用传统计算方法所得大尺度钢筋混凝土梁柱节点的抗剪承载力被明显高估了.研究表明钢筋混凝土梁柱节点的剪切变形、平均主应变和混凝土软化效应均与节点尺寸有关; 节点混凝土的软化效应随着节点尺寸的增大明显增强,影响节点的抗剪承载力.考虑节点尺寸对混凝土软化效应的影响,调整软化系数,对大尺度钢筋混凝土梁柱节点抗剪承载力的计算方法提出建议.
Abstract:
With the increase of the height of building structure,building component size is also bigger. The prediction of shear capacity in large scale beam-column joint is an important guarantee of seismic safety in high-rise building structure,and experimental results show that the shear capacity in large-scale reinforced concrete beam-column joints obtained by traditional calculation method is obviously overestimated. The experimental results indicate that the shear deformation,mean principal strain and softening effect of concrete all have obvious relationship with joint size in reinforced concrete beam-column joints. With the increase of joint size,the softening effect of concrete in joint increases obviously,which directly affects the shear capacity of joint. Considering the impact of joint size on softening effect of concrete,the softening coefficient of concrete in joint is adjusted,and the calculation method of shear capacity of large-scale reinforced concrete beam column joints is proposed.
