摘要:
钢混组合钢板梁桥负弯矩区混凝土顶板开裂问题一直以来都是困扰该类梁桥推广应用的一个难题。针对该问题,本文采用理论分析与ANSYS有限元模拟相结合的研究方法,以典型现浇钢混组合钢板梁桥为研究对象,针对梁桥结构几何参数对负弯矩区混凝土顶板开裂的影响进行系统分析,通过分析可知主梁跨径、主梁间距、桥宽变化、钢梁高度对混凝土顶板受力影响较大,混凝土厚度、横梁间距、抗剪连接件间距对混凝土顶板受力有一定影响,钢梁上下翼缘厚度及宽度和钢梁腹板厚度对混凝土顶板受力影响较小,在设计时应关注主要影响因素对混凝土顶板开裂的影响; 提出了基于性价比的组合梁桥参数优化实用方法,给出了性价比计算公式,可为结构的参数优化提供一种新的思路和参考方法; 提出了无预应力现浇钢混组合钢板梁桥混凝土顶板的裂缝控制三级标准,并针对30、35、40、45 m标准跨径的钢混组合钢板梁桥不同裂缝控制标准提出了综合控制措施,为该类梁桥负弯矩区混凝土的裂缝控制提供技术支持。
Abstract:
The cracking problem of concrete top in the negative bending moment region of steel-concrete composite steel plate girder bridge has been a difficult problem that puzzles the popularization and application of this type of bridge. For solving this problem, the research method of combining theoretical analysis and ANSYS finite element simulation was adopted in this paper. Taking the typical cast-in-place steel-concrete composite steel plate girder bridge as the research objection, and the influence of bridge structural geometric parameters on the cracking of concrete top in negative bending moment area was systematically analyzed. Through the analysis, it could be seen that the span of main girder, the spacing of main girder, the change of bridge width and the height of steel girder had great influence on the stress of concrete top. Concrete thickness, beam spacing and shear connector spacing had certain effects on the stress of concrete top. The thickness and width of upper and lower flanges of steel beam and the thickness of web plate of steel beam had little effect on the stress of concrete top. In design, attention should be paid to the influence of main factors affecting on the cracking of concrete top. A practical method for parameter optimization of composite girder bridges based on cost performance was proposed, and the calculation formula of cost performance was given, which can provide a new idea and reference method for parameter optimization of structures. A three-level crack control standard for concrete top of cast-in-place steel-concrete composite beam bridge without prestress was proposed, and comprehensive control measures were proposed for different crack control standards of steel-concrete composite steel-plate beam bridge with standard spans of 30, 35, 40 and 45 m, providing technical support for crack control of concrete in negative bending moment area of such bridges.
