Influence of Tensioning Stress to Web Cracking of Rigid Frame Bridge in Cantilever Construction

Abstract:

Cantilever construction is main mode for prestressed concrete continuous rigid frame box-girder bridges, but the diagonal cracks on web are often appeared in construction. The prestressed tension is an important part of the construction beyond doubt. This article takes a bridge under construction as the background to analyze the variation of stressed in the process of construction by MIDAS FEA. The result shows that the vertical steel stretch-drawn in advance has to be a consensus in future.
