摘要
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。
In this paper, the bond strength between steel shape and concrete, the property of force transmission of the studs welded on steel shape as well as the effect of the stirrups in the top section of encased columns under axial loading were studied. According to the tests of 22 specimens, the failure modes and conditions of occurrence of different failures, and the main factors that affect the property of force transmission were analyzed. Then the calculating equations were derived. The results calculated from the suggested equations are in good agreement with those obtained from the tests.
