Abstract: The evaluation of a welded, steel girder bridge that once crossed the Rio Puerco River near Albuquerque, New Mexico, is presented in this study. Following 44 years of service, the bridge was scheduled for total replacement ...

Abstract: A nondestructive strength evaluation of the I-40 Bridge over the Rio Grande River in Albuquerque, N.M. was completed for the New Mexico Department of Transportation (NMDOT). The I-40 Bridge is a precast, prestressed concrete ...

Abstract: A computer-based, graphical approach is presented to construct the Influence Profile for determinate bridge structures that are subjected to multiple axle loads. An Influence Profile represents the variation of an internal ...

Abstract: In New Mexico, bridges without plans are currently an issue as in other states in the US. Standard techniques cannot be used for load rating due to the lack of design plans that contain necessary information such as material ...

Abstract: In New Mexico, many reinforced concrete slab (RCS) bridges provide service on interstates I-10, I-25, and I-40. The load rating for this type of bridge largely depends on the live-load moment in the slab. Consequently, the ...

Abstract: Recent research has revealed that the nondestructive evaluation technique used most often to assess the physical condition of a bridge is visual inspection. During a routine visual inspection, observations and/or measurements ...

Abstract: This paper reports on the results from a study of vertical deflection measurement of bridges using digital close-range terrestrial photogrammetry (DCRTP). The study consisted of a laboratory and two field exercises. In the ...
