Geometric Parameters Design and Shear Buckling Strength Research of the Type 3200 Corrugated Steel Webs

摘要

The prestressed concrete composite box girder bridge with corrugated steel webs is a new type of bridge structure which has been widely used in China in recent years. This paper summarizes the development of corrugated steel webs elastic shear buckling strength theory and the corresponding methods. In order to meet the practical engineering requirements of the large height girder bridge with corrugated steel webs, the geometric parameters of the type 3200 corrugated steel webs were preliminarily designed. A reliable finite element model for the analysis of elastic shear buckling of corrugated steel webs was established, and the type 3200 corrugated steel webs were checked by finite element method.
