| Abstract: | To study the degree of influences of the internal and external temperature differences of the box girder on its cracking resistance properties,the auxiliary bridge of Sutong Bridge,a long span continuous rigid-frame box girder bridge with span arrangement(140 268 140) m,is taken as the research object and the structural spatial finite element analysis software is used to establish a spatial global structure analysis model to analyze the influences of the internal and external temperature differences on the cracking resistance properties of the girder,and the results of the analysis are also compared to those of the calculation by structural plane link finite element analysis software under similar conditions. |
