摘要:
基于位移法，考虑纵向滑移及剪力滞的影响，结合Newmark几何模型和三次广义剪力滞位移分布模式，推导适用于钢-混组合结构的有限元平面梁单元模型．结合Kelvin复合黏弹性徐变模型，分析复杂桥梁结构．研究表明，混凝土桥面板中因存在徐变，成桥后结构将产生内力重分布，对桥梁后期的正常营运造成严重影响.对九江重建组合斜拉桥进行徐变分析，计算与实测结果吻合，验证了本方法的可行.
Abstract:
Based on the geometric model of Newmark and third-order distribution pattern of generalized shear lag displacement model， in consideration of the slip and shear lag effect， the finite element model of plane beam element was derived. Applicable to steel-concrete composite structure， the model was used to analyze complex bridge in combination with the Kelvin composite visco-elastic creep model. Research results show that distribution of internal forces after the completion of bridge would change due to the creep in the bridge decks， which would affect the normal operation of the bridge. The creep analysis on the Jiujiang reconstructed composite cable-stayed bridge indicates that the calculated results are consistent with the measured data，demonstrating that the proposed method is accurate.
