Explore cutting-edge research and developments in steel fracture, namely ultra-high toughness steel and twin tub girder redundancy analysis. Understanding the fracture behavior of steel is essential for ensuring the safety, reliability, and performance of steel bridges. This session will delve into the latest advancements in assessing and improving the fracture toughness of steel as well as how ultra-high toughness steel can be leveraged as part of an integrated fracture control plan. In addition, an example implementation of reclassifying twin tub girders as system redundant members will be explored.
