Ultra-high performance concrete (UHPC) is not an ideal material for rapid repairs of bridge
expansion joints due to its slow early strength development. To mitigate this early strength …

This study proposed an interpretable ensemble learning framework to evaluate the shear
performance of perfobond shear connectors (PBLs) in steel-concrete composite structures. A …

Tensile stresses and cracks in concrete slabs induced by a hogging moment have always
been a disadvantage of steel-concrete composite structures and key issue of concern in the …

Due to the strong interface effect of continuous steel–concrete composite beams with
conventional shear connectors, the efficiency of applying pre-stress in the negative moment …

The perfobond connector is the most widely used connector in the steel–concrete joints of
long-span hybrid bridges, and the behavior of the perfobond connector group directly …

Due to the accumulated fatigue damage in steel–concrete continuous composite box
beams, a plastic hinge forms in the negative moment zone, leading to significant internal …

This study conducted fatigue tests on two 1: 3 steel truss web-concrete external joints to
investigate their fatigue performance. The fatigue failure mode of the external joints and the …

某人行景观桥为空间异型钢塔斜拉桥, 主塔中2 根箱型钢柱在四棱台混凝土基座上方交汇呈非
对称V 形, 钢柱轴线与其底端钢− 混连接面不垂直, 基座尺寸严格受制于河道防洪要求, 使塔根 …

This study aims to provide an effective method to study the behavior of a steel–concrete
composite deck. First, the structural characteristics of the composite deck and the challenges …

The core part of a hybrid truss bridge is the connection joint which combines the concrete
chord and steel truss-web members. To study the mechanical behavior and failure mode of …
