摘要
栓钉剪力连接件是保证钢梁与混凝土翼缘共同工作的关键元件,栓钉锈蚀后将直接影响组合梁的抗剪连接程度,进而影响梁的承载能力.文中将通过推出试验,研究栓钉锈蚀对其承载力的影响规律.通过对试验结果的回归分析,研究栓钉锈蚀后的抗剪承载力的计算公式.
The shear stud is a key component of steel-concrete composite structures. Stud Corrosion will influence the degree of shear connection and shear capacity. Stud corrosion and structural function deterioration of push-out specimens was studied by accelerated deterioration using a galvanstatic meth- od in this paper. By the regression analysis of experimental results, the formula was proposed for pre- diction of shear capacity of deteriorated stud shear connector.
