Prevention of torsional irregularity in steel structures via brace members

Abstract

Steel structures can be designed using moment-resisting frame systems or braced frame systems. Torsional irregularities can occur in non-symmetrical structures designed with moment-resisting steel frame systems. These torsional irregularities can be eliminated by adding braces to moment-resisting steel frame systems. In this study, X-type braces were added to the moment-resisting steel frame system with A1 torsional irregularity and torsional irregularity was prevented.
