通过１９ 个角钢埋入混凝土试件的抗拔破坏试验，分析了角钢与混凝土之间的粘结性能，研究了在轴拉荷载作用下角钢与混凝土之间的粘结应力分布情况，得出辅助锚固对角钢的抗拔承载力的影响，给出角钢最小锚固长度的计算方法
Through the tensile failure test of 19 angle steel embedded concrete specimens, the adhesive properties between angle steel and concrete were analyzed, and the bond stress distribution between angle steel and concrete under axial load was studied. The influence of the anchorage on the pull-out bearing capacity of the angle steel and the calculation method of the minimum anchoring length of the angle steel
