Lobo Co-Authors ASCE Journal of Bridge Engineering Technical Paper on Live Load Performance of Rail Transit Bridge

Our Senior Bridge Engineer John Lobo, P.E., M. ASCE, combined his knowledge of industry-standard design guidelines with field testing data to co-author a technical paper, “Live Load Distribution and Dynamic Amplification on a Curved Prestressed Concrete Transit Rail Bridge” for the American Society of Civil Engineers (ASCE) Journal of Bridge Engineering. The paper details the analysis of an in-service light rail transit bridge in Denver, which was designed using standard guidelines that do not address transit rail structures. It delves further into the findings regarding live load distribution and amplification as train speed increased, and the variations that were found as a result of the study.

Lobo brings expertise in transit structures, blast loading and hydraulic structures, and is proficient in a wide variety of analytical methods using several sophisticated analysis and design software packages. Over the course of his career, he has also worked with a variety of design codes, both local and international.
