Effect of composite action on the dynamic stability of special steel moment resisting frames designed in seismic regions
Effect of composite action on the dynamic stability of special steel moment resisting frames designed in seismic regions
Seismic assessment of steel frame structures is typically concerned with analytical modeling of the lateral load-resisting system only, ignoring the effect of composite action on its lateral stiffness and strength. Based on a recently developed database for deterioration modeling of steel beams with reduced beam sections (RBS), the effect of composite action on their bending strength and deterioration parameters (e.g. plastic rotation capacity, post capping rotation capacity, rate of cyclic deterioration) under cyclic loading can be quantified. These connections are widely used in United States in design of special steel moment resisting frames. A phenomenological model, which is able to simulate important deterioration modes when a steel component is subjected to cyclic loading, has been modified to incorporate slab effects on moment-rotation characteristics of composite steel beams. The effect of composite action on the collapse capacity of SMFs is demonstrated through a case study of an 8-story steel building.

Abstract
Seismic assessment of steel frame structures is typically concerned with analytical modeling of the lateral load-resisting system only, ignoring the effect of composite action on its lateral stiffness and strength. Based on a recently developed database for deterioration modeling of steel beams with reduced beam sections (RBS), the effect of composite action on their bending strength and deterioration parameters (e.g. plastic rotation capacity, post capping rotation capacity, rate of cyclic deterioration) under cyclic loading can be quantified. These connections are widely used in United States in design of special steel moment resisting frames. A phenomenological model, which is able to simulate important deterioration modes when a steel component is subjected to cyclic loading, has been modified to incorporate slab effects on moment-rotation characteristics of composite steel beams. The effect of composite action on the collapse capacity of SMFs is demonstrated through a case study of an 8-story steel building.
