摘要
基于有效弹性模量法,文章建立了有限元模型,计算分析了大跨度钢管混凝土拱桥徐变对结构位移、内力重分布以及动力特性的影响。
Based on effective tangent modulus method,this paper establishes finite element model, calculates and analyzes the impact of the gradual change of long span concrete filled steel tubular arch bridges on their structural displacement, re-division of internal force, dynamic characteristics.
