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: Rate-independent and rate-dependent models are presented for the hysteretic shear stress-strain behavior of elastomeric damping materials. A rate-independent hysteretic model, called the general asymptote and power function ...

Abstract: This paper presents research on seismic design of steel special moment resisting frames (SMRFs) with supplemental elastomeric dampers. The SMRF properties and damper design criteria are varied to illustrate their effects ...

Abstract: Horizontally 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 and conveniently transformed to self-equilibrating ...
