摘要
Abstract
With orthotropic steel deck of No. 3 Bridge in Erdos Ulan Moron Lake Area as the research object, referring to Japan's Specifications for Highway Bridges and U. S. AASHTO Specification, spatial rod model is established using Midas/Civil software to analyze the first system and spatial plate beam model is established using ANSYS software to analyze the second and third system. It is shown that the strength and rigidity of bridge deck, U rib and large & small beam are all within the limits and have large margin. Orthotropic steel bridge deck is under complicated stress and must be analyzed using refined finite element method. The strength and rigidity of orthotropic bridge deck shall be attached much importance to fully understand the real stress state of the structure.关键词
