Abstract: Effective stability bracing of beams can be achieved by either preventing lateral movement of the compression flange or restraining twist of the beam cross section. Bracing that restrains twist is aptly referred to as ...

Abstract: Effective bracing systems for columns and beams exist in many forms, including point bracing and continuous bracing. Employing continuous bracing formulations for cases with point braces provides an attractive solution ...

Abstract: Cross frames and diaphragms are critical elements for the stability of I-shaped steel bridge girders during construction. The AASHTO specifications are relatively vague with regards to the stability design requirements of ...

Abstract: Narrow width I-girder systems with relatively long lengths are susceptible to global lateral-torsional buckling, which is a mode that is not generally sensitive to the spacing between cross frames or diaphragms. This ...

Abstract: Establishing the strength requirements for stability bracing generally requires large displacement analyses on imperfect systems. In computational studies on stability bracing, choosing the critical shape of the imperfection ...

Abstract: A critical design stage for steel girders occurs during casting of the concrete bridge deck, when the noncomposite steel section must support the wet concrete and the entire construction load. Although a composite box ...

Abstract: A fracture-critical bridge along Interstate Highway 35 with a relatively high volume of traffic had exceeded its original design life and was monitored before and after a repair was implemented to strengthen the bridge. ...

Abstract: Light gauge metal decking is commonly used in the building and bridge industries for concrete formwork. In addition to supporting the concrete, the metal forms also improve the lateral-torsional buckling capacity of the ...

Abstract: Trapezoidal steel box girders are often used in curved bridges due to the large torsional stiffness that results from the closed cross section. However, the torsional loading on the box girders can cause the cross section ...
