摘要:
基于框架分析法的基本原理,结合波形钢腹板箱梁的结构特点和力学特性,建立了适用于其桥面板横向内力的计算模型.该计算模型能够反映横向框架作用和箱梁畸变效应对桥面板横向内力的影响.通过与相关室内模型试验数据和有限元分析结果的对比可知,框架分析法计算值与有限元结果、试验值吻合,误差均在10%以内,验证了此计算模型的正确性.并采用上述模型分析了钢腹板线刚度变化对桥面板横向内力的影响,结果表明在波形钢腹板箱梁截面上的腹板间距确定的条件下,波形钢腹板与混凝土顶板的线刚度比是影响桥面板横向内力的重要因素.
Abstract:
Based on the basic principles of the frame analysis method and structural characteristics and mechanical properties of box girders with corrugated steel webs, a model which can be applied to the calculation of the transverse internal force of bridge deck is established. This calculation model can reflect the influence of the transverse frame effect and the distortion effect of box girders on the transverse internal force of bridge deck. By comparing with indoor model test results and data of finite element analysis, it is shown that the calculated value of the frame analysis method is consistent with the finite element results and experimental values, and both the errors are both less than 10%, which verifies the correctness of the calculation model. Furthermore, the model is adopted to analyze the influence of linear stiffness change of corrugated steel webs on the transverse internal force of bridge deck. Results demonstrate that the linear stiffness ratio of steel web and bridge deck is the important influence factor when the web spacing in the cross section is certain.
