摘要:
为研究端部锚固条件对波纹钢-混凝土组合板静力性能的影响,通过静力试验对比设置/未设置端部锚固组合板的破坏模式、荷载-挠度曲线、荷载-滑移曲线; 采用ABAQUS软件建立波纹钢-混凝土组合板纵剪性能有限元模型,通过参数分析量化端部锚固条件对波纹钢-混凝土组合板纵剪性能的影响,并提出适用于波纹钢-混凝土组合板的设计方法.结果表明:设置端部锚固可有效提高波纹钢-混凝土组合板的抗剪承载力,与无端部锚固组合板相比,设置端部锚固的组合板抗剪承载力增加31.5%; 厚度由120 mm增大至160 mm,抗剪承载力增大30.5%; 计算跨度由2 700 mm提高至3 300 mm,抗剪承载力降低31.7%; 提出的设计方法可有效预测波纹钢-混凝土组合板的抗剪承载力,计算结果与试验结果误差在10%以内.
Abstract:
To study the effect of end anchoring conditions on the static performance of corrugated steel-concrete composite slabs, two sets of full-scale specimens of corrugated steel-concrete composite slabs were designed and fabricated, and the failure modes, load deflection curves and load slip curves of composite panels with or without end anchors are compared through static tests. The finite element model of longitudinal shear performance of corrugated steel-concrete composite slabs was established by ABAQUS software, and the reliability of the model was verified by experimental data. The influence of end anchorage conditions on the longitudinal shear performance of corrugated steel-concrete composite slabs was quantified by parametric analysis, and design method suitable for corrugated steel-concrete composite slabs was proposed. The results show that the longitudinal shear failure of the corrugated steel-concrete composite slab without end anchorage occurs under the action of external load. Setting the end anchor can effectively improve the shear bearing capacity of the corrugated steel-concrete composite slabs, and the shear bearing capacity of the set end anchoring composite slab is increased by 31.5% compared with the endless anchoring composite slab. The proposed design method can effectively predict the shear bearing capacity of corrugated steel-concrete composite slabs, and the error between the calculation result and the test result is within 10%.
