Fatigue-Prone Details in Steel Bridges

Methods for Better Assessment of Fatigue and Deterioration in Bridges and Other Steel or Concrete Constructions

Large metal and concrete structures suffer by various kinds of deterioration, and accurate prediction of the remaining life is important. This paper informs about two methods for its assessment. One method, suitable for steel bridges and other constructions exposed to fatigue, monitors the loads and damage accumulation using information systems for the operation and the finite element model of ...

finite element based fatigue assessment of corrugated steel web beams in highway bridges

this paper presents a finite element analysis and its related experimental test of corrugated steel web beams subjected to fatigue loading. a particular focus in this study was set on the fatigue failure arising from the web-to-flange welded joint of the corrugated steel web beam. a detailed three-dimensional finite element model which explicitly includes the geometry of the web-to-flange welds...

Economical Steel Plate Girder Bridges

As a service to the bridge design profession, Bethlehem Steel has conducted hundreds of studies of steel plate girder bridges using its Preliminary Bridge Girder Optimization Program. The program is unique because it optimizes plate girder designs on the basis of least cost, not least weight. An evaluation of many study results leads to a number of guidelines which are offered in this paper. Wh...

Reducing Fabrication Errors in Steel Bridges

At the University of Kansas, we are collecting cases and advice and making it available by computer. The software, Fabrication error Indexed eXamples and Solutions (FIXS), is a knowledge-based system to provide quick, possible solutions to fabrication errors suitable for use by multiple DOTs. The sharable database can lead to standardized solution procedures that would expedite bridge fabricati...
