Steel Structures in Fire: New Approaches for Modeling and Analysis [N32A]

Evaluating the stability of steel structures under fire-induced thermal loads is challenging. When the system components are subjected to high temperatures and steep non-uniform thermal gradients, connections and members are often required to resist large compressive forces induced by restraint against thermal expansion, followed by large deflections, rotations, axial deformations and/or potential destabilization. This session will present reduced-order modeling approaches to enable modeling of large systems under fire conditions.
