Abstract:

This research developed and demonstrated a new approach to the accelerated fabrication of resilient steel bridges—built-up press-brake formed tub girders (PBTGs). Built-up PBTGs are comprised of webs that are cold bent via a press brake and bolted to separate, flat bottom and top flanges. This investigation included (1) designing and building two demonstration bridges, (2) measuring the behavior of the demonstration bridges as experimental evidence demonstrating behavior, and (3) developing a kit-of-parts system to facilitate future adoption of this system. Research culminated in two completed vehicular bridges that are in use, validated numerical modeling approaches for design, a kit-of-parts system, and a summary of the lessons learned.
