Processing analysis of deflection of main girder for long-span concrete continuous girder bridge with mixed arrangement of internal and external tendons
摘要
Abstract
To eliminate the diseases of excessive deflection of main girder of long-span con-crete continuous girder bridge induced by shrinkage and creep of concrete and prestress loss,a finite element model of a long-span continuous rigid frame bridge in Anhui province was built to analyze the effect of coupling the shrinkage,creep and prestress loss on long-span concrete continuous girder bridge by using creep criteria and temperature change of ANSYS software to simulate shrinkage and creep of concrete,studying the influence of ex-ternal tensioning on preventing deflection of main girder.Analytical method of deflection of main Girder for long-span concrete continuous girder bridge with mixed arrangement of in-ternal and external tendons are obtained.关键词
