摘要
分析比较了混凝土受拉构件开裂机理与非预应力连续组合梁桥负弯矩区混凝土桥面板开裂机理的异同,给出了连续组合梁桥混凝土板开裂对组合梁截面力的分配的影响及其与混凝土板平均应变、全截面曲率的关系公式。
This paper analyzes and compares the similarities and differences of cracking mechanism between concrete tensile element and concrete slab in negative moment area of nonprestressed continuous composite girder bridge, and gives influences of the cracked concrete slab of the continuous composite girder bridge upon the distribution of stress in section of the composite girder, and relationship between the influences and the average strain and full section curvature rate of the concrete slab.
