Abstract: A lateral bracing system is installed at the top flange level of a steel tub girder to form a quasi-closed box, thereby increasing torsional resistance and retaining the original box shape. A single diagonal (SD) type or ...

Abstract: The current American Association of State Highway and Transportation Officials (AASHTO) standard specifications for highway bridges and AASHTO LRFD bridge design specifications stipulate the computation of the design load ...

Abstract: Trapezoidal steel box girders (also known as tub girders) may be at their critical stage during construction because the noncomposite steel section must support both the wet concrete and the entire construction load. A ...

Abstract: This paper revisits a fundamental assumption used in most classical failure theories for postbuckled web plates under shear, namely that the compressive stresses that develop in the direction perpendicular to the tension ...

Abstract: Design methods for tapered members of multiple materials with nonrectangular cross sections are not available. This finite‐element study of straight, single‐tapered I‐beams was conducted to aid in developing a rational ...

Abstract: Nonlinear analyses have been conducted on three-dimensional finite element models of transversely stiffened plate girder web panels (without longitudinal stiffeners) subjected to pure shear, including the effects of initial ...

Abstract: The imperfect trench installation method is used to reduce earth pressure on buried concrete pipes. Few quantitative refinements to the imperfect trench installation method, however, have been added since the fundamental ...

Abstract: In 1992 the Federal Highway Administration, along with 13 states, began a project to study the behavior of horizontally curved steel bridges. The project is referred to as the Curved Steel Bridge Research Project and ...

Abstract: Horizontally curved I-girders are subjected to combined vertical bending and torsion under gravity loading alone. The torsional behavior of open I-shaped girders is commonly and conveniently equated to self-equilibrating ...
