Welding of Painted Steel-Steel Bridges.

Steel versus Steel-reinforced Concrete Bridges: Environmental Assessment

Bridge material selection has traditionally been b~ed on e.ngineering and economi~ criteria. With the increasing interest of the public, industry, and government m sustainable:: development, en~lronmental. assessment in construction is becoming more important. However, we need metrtcs and data on deSign alternatives for effective decision making. In this paper, we present results of a life cycl...

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...

Nondestructive Testing and Evaluation of Steel Bridges

Nondestructive evaluation (NDE) is a means of evaluating structural components without damaging them. It can be used to evaluate structural systems, as well as specific structural components. Nondestructive testing is particularly useful for evaluating inservice bridges, since the bridges can remain in tact and open to traffic during the inspection and evaluation period. The NDE methods discuss...

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...
