摘要
通过钢板-混凝土的双面剪切试验,研究了冻融循环作用对粘钢混凝土双面剪切性能的影响规律及破坏特征,并分析了冻融环境下界面承载力和峰值应变的变化.结果表明:钢板-混凝土双面剪切试件在经历0次、15次、25次、40次、50次、75次、100次冻融循环后进行双面剪切试验,试件的破坏均为脆性破坏,主要破坏形式为胶体与钢板剥离、胶体与混凝土剥离两种形式.
Abstract
The effects of freeze-thaw cycles on the double-sided shear properties of reinforced steel concrete were studied by double-sided shear tests of steel plate and concrete.The changes of interface bearing capacity and peak strain under freeze-thaw conditions were also analyzed.The results show that after 0,15,25,40,50,75,100 freeze-thaw cy-cles,double-sided shear specimens of steel plate and concrete are subjected to double-sided shear tests.The failure of specimens is brittle,and the main failure forms are colloid and steel plate stripping and colloid and concrete stripping.
