Abstract: Major engineering failures act as a catalyst for change in standards of practice and therefore create the opportunity for establishing better ethical practices for the profession. When examining ethics in engineering ...

Abstract: A rule-based system for resolving fabrication errors in steel highway bridges, the Bridge Fabrication Error Solution Expert System (BFX), is in operation at the Kansas Department of Transportation. The set of more than 100 ...

Abstract: Welded plate girder bridges built before the mid-1980s are often susceptible to fatigue cracking driven by out-of-plane distortion. However, methods for prediction of secondary stresses are not specifically addressed by ...

Abstract: This paper studies a Kansas Department of Transportation welded plate girder bridge that developed fatigue cracks at small web gaps close to the girder top flange. Repair had been previously performed by softening the ...

Abstract: Traditional methods of bridge deck condition assessment are slow, labor‐intensive, intrusive to traffic, and unreliable. Two new technologies, radar and infrared thermography, which have recently been introduced, show ...

Abstract: This study determined an explicit tolerance for bottom flanges of tub girders giving computed first yield moment including the strength reduction due to initial out-of-flatness of tub girders higher than the flexural design ...

Abstract: An innovative self-shoring staged construction method was developed to build the world’s longest reinforced composite concrete arch bridge across the Yangtze River at Wanxian, in Chongqing, China. The method uses a steel ...

Abstract: A knowledge-based system for resolving fabrication errors in steel highway bridges is in operation at the Kansas Department of Transportation (KDOT). The Bridge Fabrication Error Solution Expert System (BFX) addresses ...
