Bending Strength of a Horizontally Curved Composite I-Girder Bridge

摘要: AbstractHorizontally curved I-girders are subjected to combined vertical bending and torsion under gravity loads alone. The torsional behavior of open I-shaped girders is commonly conveniently transformed self-equilibrating lateral flanges. interaction flange reduces the moment–carrying capacity section. equations for predicting nominal strength horizontally compact-flange sections moment have been derived. Singly symmetric composite noncomposite cross in positive negative zones, respectively, considered. These criteria based purely on static equilibrium section with no secondary amplification limitations applicability derived toward design use demonstrated analyzed.
