Inelastic behavior of orthotropic steel deck stiffened b U-shaped stiffeners

摘要

Owing to its high strength and stiffness, the orthotropic steel deck system has been widely used in the construction of long-span steel bridges. However, due to esthetic and economic considerations, slender types of ortotropic bridge have become very popular in recent years. Consequently, the stability of the orthotropic steel deck system under traffic load becomes More critical. Although the instability problem of the orthotropic steel deck system due to Flexural compressive stress has been recognized for years, current bridge design specifications Do mot clearly specify the criteria to prevent local buckling of the orthotropic deck system.
