摘要
介绍了预应力结构全过程分析中预应力钢筋或钢束的一般模型 ,并针对曲线预应力混凝土桥梁张拉施工阶段结构的实际摩擦系数进行了分析计算 .由曲线预应力混凝土桥梁张拉阶段摩擦系数的分析结果表明 ,一些不确定因素造成了实际摩擦力大于理论值 。
This paper introduced a general model of prestressing tendons, which can be used to analyse any prestressed structure. As an application to practical engineering, a long span curved prestressed concrete bridge was analyzed in its tension segment construction. From the analysis results of the bridge, the practical values of friction are greater than the theoretical ones because of some uncertainties, which is of universal significance.
