摘要:
针对T型钢与混凝土黏结滑移的问题,进行了8个T型钢混凝土试件的推出试验,主要考虑混凝土强度、混凝土保护层厚度、横向配箍率3个因素的影响,得到了型钢应变、黏结强度、滑移沿锚固深度的分布规律以及不同锚固深度处的黏结滑移曲线。综合考虑这3个影响因素,统计回归出了特征黏结强度和特征滑移值的计算公式; 引入2个位置函数,建立了考虑位置函数的黏结强度-滑移本构关系。试验结果表明:混凝土强度、混凝土保护层厚度、横向配箍率均对黏结强度有显著影响。
Abstract:
Considering the influences of three main factors including concrete strength, thicknesses of concrete cover as well as transverse stirrup ratios, the push-out tests of 8 specimens on the bond and slip behaviors between T-section steel and concrete were carried out to obtain the regularities of distribution of steel strain, bond strength and slip along the embedded position and bond and slip curves in different embedded positions. Synthetically considering the three factors, a set of calculative formulas of three characteristic bond strengths and three characteristic slippage values were presented by regression analysis, meanwhile, two position functions were introduced to build bond strength and slip constitutive relations. The experimental results show that the three main factors have obvious influence on bond strength.
