本文主要对劲性砼柱端部型钢与砼的粘结力和栓钉对于力传递扩散性能进行了研究。根据22个试件的试验结果,提出了各种破坏形态及发生的条件,分析试件的受荷特性及工作机理并讨论影响力扩散性能的主要因素。给出计算模式,建立了力扩散范围内的计算公式,并与试验结果比较,符合程度良好。
This paper mainly studies the adhesion force and the stud force transfer diffusion properties of the steel end-section steel and concrete. Based on the test results of 22 specimens, various failure modes and conditions were proposed. The loading characteristics and working mechanism of the specimens were analyzed, and the main factors affecting the diffusion performance were discussed. Given the calculation mode, the calculation formula within the force diffusion range was established, and compared with the test results, the degree of compliance was good.
