Open publisher page 0 citations

Abstract

Continuous-rigid-frame-arch bridges have such advantages as the high stiffness of continuous rigid-frame bridges and the stronger spanning capacity of arch bridges.This paper takes a continuous-rigid-frame-arch bridge as the object of study,and establishes its three dimensional finite element model using the software ANSYS to study the stress distribution of the box girder in the cross direction and the thermal stresses in the bridge.
