SRC-RC竖向混合结构转换柱承载力与延性性能分析
|
摘要
以16根转换柱试件和1根钢筋混凝土柱对比试件的低周反复荷载试验为基础,分析了转换柱的承载力与延性性能。研究了钢与混凝土之间的相互作用方式,确定了型钢局部存在对转换柱力学性能的影响。型钢的配钢率、轴压比、型钢延伸高度及体积配箍率是影响承载力与延性性能的主要因素:配钢率越大,转换柱的承载力越大,位移延性系数越小;轴压比越大,转换柱的承载力越大,位移延性系数越小;型钢延伸高度对转换柱的承载力影响较小,而位移延性系数随着型钢延伸高度的增加呈现出先升后降的变化规律,当延伸高度达到3/5的柱高时位移延性系数达到最大值;随着体积配箍率的增加,转换柱的承载力与位移延性系数同时增大,增长速率与配钢率有关,配钢率较大试件的承载力与位移延性系数随体积配箍率的增长速率更快。
Experiments of 16 transfer columns and 1 reinforced concrete column under low cyclic reversed loading were carried out.The interaction between concrete and shape steel was analyzed,which showed the effect of partially extended shape steel on transfer column.Volumetric ratio of stirrups,axial compressive ratio,extension length of shape steel and area ratio of shape steel have obvious effect on bearing capacity and ductility performance of transfer column.Bearing capacity increases with the increase of shape steel section and axial compressive ratio,but displacement ductility degenerates at the same time.Extension length of shape steel has little effect on bearing capacity,but displacement ductility changes with the increase of the extension length of shape steel,enhancing at first and then reducing,reaching peak value when extension length of shape steel gets close to three fifths of column height.Bearing capacity and ductility are both enhanced while more stirrups are deposited.
