摘要

摘要: 闭口型压型钢板利用其独特的板肋构造，在保持板面平整的同时，相较于传统平钢板具有更高的屈曲承载力、平面外刚度，并能更好地与混凝土协同工作，可用于提升墙面围护结构、抗侧力构件及钢板混凝土组合结构的受力性能。为明确其面内剪切受力机理，设计并完成了两片闭口型压型钢板在纯剪荷载作用下的对角加载试验，板肋分别采用竖向放置（DPS-V）和45°斜向放置（DPS-D）。通过试验观察了钢板的屈曲形态、变形发展过程及破坏模式，并结合有限元分析揭示了其工作机理。结果表明；闭口型板肋为板带提供了有效的边界约束作用，避免了整体贯穿型屈曲变形；两种板肋布置方式的试件均呈现板带局部屈曲特征，其中DPS-V表现为剪切屈曲，DPS-D表现为受压屈曲；在板肋边界约束作用下，板带能够发挥屈曲后强度；但局部拉力带发展过程中对板肋产生的拉力使得板肋弯扭失稳，并导致试件整体破坏；DPS-V的剪切荷载主要由板带承担，而DPS-D则由板带与板肋共同承担且表现出显著的各向异性特征，其在斜向受拉状态下的承载力较斜向受压状态下提升了38%；DPS-V初始刚度与承载力略低于DPS-D，但其在峰值后表现出更优的延性与变形能力。基于叠加原理分别提出了两类钢板的抗剪承载力计算公式，计算结果与试验值的相对误差在4%以内，可为工程设计提供参考。

Abstract: Dovetail profiled steel sheets are characterized by a unique rib configuration that ensures a flat plate surface. Compared with conventional flat steel plates， they offer higher buckling resistance， greater out-of-plane stiffness， and more effective interaction with concrete. These superior properties render them well-suited for enhancing the mechanical properties of wall claddings， lateral force-resisting components， and steel-concrete composite structures. To clarify their in-plane shear mechanism， pure shear diagonal loading tests were conducted on two dovetail profiled steel sheet specimens： DPS-V with vertically oriented ribs and DPS-D with ribs inclined at 45°. Experimental observations were focused on buckling modes， deformation evolution， and failure modes， while finite element analysis （FEA） was employed to further elucidate the underlying working mechanism. The results indicated that the profiled ribs provided effective boundary restraint to the plate strips， thereby inhibiting global penetrating buckling. Both specimens exhibited localized buckling within the plate strips， with DPS-V undergoing shear buckling and DPS-D experiencing compressive buckling. Owing to the boundary restraint provided by the ribs， the plate strips were capable of developing post-buckling strength； however， the tensile effect induced by the formation of local tension fields ultimately led to flexural-torsional instability of the ribs， resulting in overall failure. The shear resistance of DPS-V was primarily provided by the plate strips， whereas that of DPS-D was derived from the combined action of the plate strips and ribs， exhibiting significant anisotropic behavior—its bearing capacity under diagonal tension was 38% higher than that under diagonal compression. Although the initial stiffness and ultimate bearing capacity of DPS-V were slightly lower than those of DPS-D， DPS-V demonstrated superior ductility and deformability beyond the peak load. Based on the superposition principle， design formulas for predicting the shear capacity of the two types of steel sheets were proposed. The relative error between the calculated and experimental values was within 4%， providing a reliable reference for the engineering design of such components.
