Abstract
A type of new open-web continuous rigid frame bridge,has been proposed and applied for patent by CCCC Second Highway Consultants Co.Ltd in recent years.For open-web region,the an-gleαbetween its lower chord and pier has a significant impact on the stress of zoon and mechanical property of open-web region.In this paper,different angles of open-web region for bridge closure process are simulated based on Guizhou Beipanjiang Bridge,using ANSYS software,and the force and deformation of the major components of open-web region are contrasted and analyzed.The results show that mechanical performance of hollow region is relatively good and deflection of closure point is relative minimum when the angle αis among 53°to 60°for this type of bridge.关键词
