摘要
混凝土的徐变对先简支后结构连续梁桥的变形及内力影响较大,在设计和施工中不可忽略。对先简支后结构连续梁桥的徐变进行理论计算,并通过举例应用分析混凝土徐变对其结构内力及变形的影响规律。
Creep of concrete remarkably affects deformation and internal force of simply supported and structure continuous beam bridges and should not be ignored in design and construction. This paper performs theoretical calculation for creep of simply supported and structure continuous beam bridges, and analyzes the laws of influences of concrete creep on internal stress and deformation of structure by means of application of examples.
