为解决传统钢-混组合梁由于混凝土板本身缺陷所引起的桥面板开裂问题,提出一种性价较优的钢-UHPC组合梁桥面板截面形式,以某桥为工程背景设计了4种桥面板方案,即矮胖型带肋板方案、瘦高型带肋板方案、矩形平板方案、华夫板方案,利用ABAQUS进行了桥面板影响线及静承载能力分析,得到了以下结论:(1)桥面板轮载应力影响范围是局部的,纵桥向作用于两相邻横隔板之外的荷载对该两横隔板间跨中桥面板各点的应力几乎无贡献,横桥向作用于距某板肋超过横隔板间距的荷载对该板肋及其附近面板的应力几乎无贡献,而纵隔板上部的板肋荷载横向影响范围较广,约为2倍横隔板间距;(2)各方案桥面板主拉应力值较大区域集...

In order to solve the problem with the bridge deck cracking caused by the concrete plate defects itself in the traditional steel-concrete composite beam and to find a cost-effective steel-UHPC composite beam bridge deck section,four kinds of bridge deck scheme were designed with a bridge as the engineering background,namely pyknic-type rib scheme,lanky-type rib scheme,rectangular plate scheme and waffle slab scheme,respectively.The influence line and static bearing capacity of bridge deck was analysed by ABAQUS,and the conclusions are as follows:(1)The stress influence range in bridge deck und...
