摘要
对钢桥面铺装沥青混合料材料进行循环荷载下的弹塑性分析。研究显示复合梁试件计算结果与极限加载试验结果基本一致。与弹性模型的计算结果对比说明运用弹塑性理论对铺装层材料力学性能进行改进是合理的。在等荷载加载情况下,本研究计算了复合梁试件弹性模型和弹塑性模型的挠度和应力、应变,比较分析了两种模型在相同条件下的受力变形特性。
The elasto-plastic properties of asphalt concrete of steel deck pavement are analyzed under cyclic load. The calculated result of composite beam is basically consistent with the ultimate tensile test one, and it shows that it is reasonable to use elasto-plastic method in the research of steel deck pavement material. The deflection, stress and strain elasto plasticity properties of composite beam are also analyzed, and compared with the elasticity model under the same load.
