Spatial analysis on the mechanical behaviors of steel-concrete composite beam of long-span cable-stayed bridge
【摘要】 结合福州市青洲闽江特大桥的工程实践,对大跨度迭合梁斜拉桥在轴力和弯矩共同作用下的钢-混凝土迭合梁截面受力状态和混凝土桥面板有效宽度进行空间有限元数值分析和理论研究,提出简化钢-混凝土主梁受力状态分析的方法.
【Abstract】 Based on the construction of Qingzhou Ming River’s bridge in the city of Fuzhou,this paper made the spatial finite element numerical analysis and the theoretic research on the mechanical behaviors of steel-concrete composite beam and effective width of concrete slab under the function of axial force and the bending moment.According to the results of the research, the paper puts forward a method to simplify the mechanical behaviors analysis of steel-concrete composite beam.
