Nondestructive Testing of a Two Girder Steel Bridge
Due to geometry and traffic safety considerations, the I-40 bridges over the Rio Grande were scheduled to be demolished in the fall of 1993. This created a unique opportunity for testing. The bridges are classified as .fracture critical,. two girder steel bridges. The bridges were tested to determine the effect of defects on the redistribution of loads, on the load capacity, and on the potential for collapse. Two nondestructive techniques, resonant ultrasound and modal analysis, were tested on the bridge. Base line data was accumulated for the undamaged bridge. Then four different levels of damage were introduced in the middle span of one of the girders. Data was accumulated at every stage. The final stage was a near full depth crack in the girder. Static tests and forced vibration tests were performed on the structure. This is an on-going project. This paper describes the preliminary stages of the project. Full results of the testing, i.e., data obtained from the testing as well as evaluation and assessment of the results will be published at a later date.
