摘要:
为掌握预应力混凝土斜拉桥主梁在运营荷载作用下的受力情况,根据其构造特点,将结构划分为2个结构体系,分别建立整体结构尺度模型和局部构件尺度模型,并采用子模型法进行跨尺度模型的衔接.以五河口斜拉桥的预应力混凝土主梁为例,进行了车轮荷载作用下的主梁局部应力分析,与该桥成桥静载试验的测试结果对比表明,计算结果与试验结果吻合良好,说明该计算分析方法实用、可行,从而为进行预应力混凝土斜拉桥在运营荷载作用下的受力特性分析提供了一种便捷、可行的途径.
Abstract:
The two-system analysis method for local stress of prestressed concrete main girder is employed to investigate the mechanical characteristics of the main girder for prestressed concrete cable-stayed bridge under vehicle loads. According to the configuration characteristics of the prestressed concrete box girder, full-scale structural model and local-scale member model are built respectively. On basis of these two models, the local stress distributions of the girder for Wuhekou cable-stayed bridge under vehicle loads are calculated using submodeling method. The calculation stress values are proved to be accurate and reliable by the measurements of field test. Accordingly, the analysis method for the mechanical characteristics of prestressed concrete cable-stayed bridge under vehicle loads by submodeling method is provided.
