Steel structures when exposed to fire develop significant fire induced forces and deformations, and these effects are to be properly accounted for in evaluating realistic response of structural systems. The current design methodologies are based on prescriptive approach which does not take into consideration the fire induced forces that develop in steel beamcolumns. To overcome these drawbacks, a performance based fire design guidelines for steel beam-columns and restrained beams is developed as part of a collaborative research project between Michigan State University (MSU) and Princeton University (PU). MSUs research was focused on beams that transform into beam-columns, while PU focus was on columns that transform into beam-columns. This report presents guidelines for fire design of restrained beams. A companion report entitled, Guidelines for Predicting the Capacity and Demand of teel Beam-Columns under Fire: Part 1, Perimeter Columns, is submitted by authors at Princeton University (Drs. Garlcok M., Quiel S., Paya-Zaforteza I.).
