针对抗剪需求较大的钢-混凝土组合结构,改进了一种带横向焊钉的承压型组合剪力键.设计并开展了 10个承压型组合剪力键和 1个非承压型组合剪力键单调推出试验,明确了混凝土端部承压、混凝土强度、肋板厚度、肋板孔径和焊钉直径对承压型组合剪力键失效模式和破坏过程的影响.建立了承压型组合剪力键有限元模型,在结合试验验证仿真模型可靠性的基础上,进一步揭示了承压型组合剪力键受力机理.以试验变量为基础,建立并分析了 108个承压型组合剪力键有限元模型,推导了承压型组合剪力键极限承载力与各参数变量之间的线性关系,对极限承载力分析结果进行多元线性回归提出了承压型组合剪力键极限承载力计算...

A compressive composite shear connector with transverse studs is developed for steel-concrete composite structures with high shear resistance. Ten compressive composite shear connectors and one non-compressive composite shear connector were designed, and monotonic push-out tests were carried out. The effects of concrete bearing at the end of rib plate, concrete strength, rib thickness, rib hole diameter and stud diameter on the failure mode and failure process of compressive composite shear connectors were investigated. The finite element model...
