摘　　要：为了进一步研究型钢与高强混凝土柱黏结滑移的工作性能,采用ABAQUS软件及文献中已有的试验数据,根据黏结滑移的本构关系,建立了型钢高强混凝土柱的有限元模型,该模型的模拟结果与文献中的试验结果吻合较好。运用型钢高强混凝土柱的模型对不同的钢材型号、混凝土强度和型钢截面形状进行参数分析。结果表明:当试件的混凝土强度和型钢截面形状不变时,钢材型号的改变对型钢与混凝土的黏结强度影响不大;当试件的钢材型号与型钢截面形状不变时,混凝土强度越高,型钢与混凝土的黏结强度越大;当试件的钢材型号与混凝土强度不变时,型钢与混凝土的接触面积越大,其黏结强度越大。In order to further study the working performance of bond-slip between section steel and high-strength concrete column, the finite element model of high-strength concrete column of section steel was established according to the constitutive relationship of bond-slip using ABAQUS software and literature, and the simulation results of the model were in good agreement with the experimental results in the literature. The model of section steel high-strength concrete column was used to analyze the parameters of different steel types, concrete strength and section shape. The results show that when the concrete strength of the specimen and the cross-sectional shape of the section steel are constant, the change of steel type has little effect on the bonding strength between the section steel and the concrete. When the steel type of the specimen is constant as the cross-sectional shape of the section steel, the higher the strength of the concrete, the greater the bonding strength between the section steel and the concrete;When the steel type and concrete strength of the specimen remain unchanged, the larger the contact area between section steel and concrete, the greater its bonding strength.
