摘要
应用换算弹性模量和荷载换算系数 ,建立了计算连续梁桥徐变次内力的计算模型。本法具有概念明确、易于用有限元法计算程序进行计算。
Applying the conversion elastic modulus and conversion coefficient of load, the computer model for calculation of creep secondary internal force for continuous beam bridges is established. This method has advantages of clearing concept, easy calculation by finit element computer program, higher precision and wide applicability for continuous beam bridges with different construction technique.
