Co-authors Joe Diekfuss, Ph.D., P.E. (pictured at right), R.A. Smith National structural engineer, and Chris Foley, Ph.D., P.E., Marquette University Professor and Chair, Department of Civil, Construction and Environmental Engineering, recently published three articles in the American Society of Civil Engineer’s (ASCE) Journal of Structural Engineering. The articles provide detailed summaries for portions of a recently completed research effort funded by the Wisconsin Highway Research Program and conducted at Marquette University.

The research focused on formulating a reliability-based approach for prescribing inspection intervals for mast-arm sign support structures throughout the State of Wisconsin. The results can be used by the engineering community to establish inspection intervals that better align inspection needs with limited fiscal and human resources.

The inspection intervals for each sign support correspond to user-specified levels of fatigue-induced cracking risk within their welded tube-to-plate connections. The fatigue-induced cracking risk is dependent upon a number of variables including location of the structure within the state, orientation of the mast-arm relative to north, fatigue detail category used at its tube-to-plate connection, the amount of signage it supports and the length of time it has been in service.
