• Abstract:
  The use of weathering steel in steel bridge structures provides potential advantages in terms of improved durability and lower maintenance costs. However, among TxDOT personnel there are disparate opinions about how well the material performs. Some contend that it performs well in most environments, and others contend that it does not perform at all, but there is little scientific basis for either opinion. The purpose of this research was to examine, quantify, and publicize the performance of weathering steel as used in TxDOT bridge structures. A thorough analysis of weathering steel's performance in various locations was performed. In areas where it performs well, it will be promoted as an economical means of construction. In areas where it does not do so, it may be prohibited. In areas that are questionable, the engineer will have performance information that can be used to make the appropriate determination. In addition, field examination showed that weathering steel bridges, if not properly designed and detailed, caused staining of stone and concrete abutments. Recommendations to prevent or minimize such staining are also included.
