摘要: 根据曲梁的弯曲刚度,提出了等代跨长的概念,并将连续曲梁桥的空间分析转化为平面杆系结构的内力分析.概念明确、计算简便、精度较高,可供设计应用.

关键词: 曲线梁, 弯曲刚度, 等代跨长, 跨径修正系数

Abstract: Based on the flexural rigidity of curve box girder,This paper proposes the concept of equivalent span,and transforms the space analysis of continuous curve box girder into the foree analysis of plaae structure.This method is clear-cut and simple with high precision,therefore,it can be applied to practice.

Key words: curve box girder, flexural rigidity, equivalent span, corrective coefficient for span
