Abstract:
Steel moment-resisting frames are among the most reliable structural systems for resisting seismic and dynamic loads due to their high ductility and load redistribution capacity. Central to their performance is the beam-column joint, a critical region where axial forces, bending moments, and shear stresses converge. The performance of these joints under cyclic loading, such as during an earthquake, plays a decisive role in the overall structural response and failure mode. This study presents a comprehensive finite element analysis (FEA) of steel beam-column joints subjected to cyclic lateral loading using ABAQUS/Standard 3D Experience R2019x. The objective was to evaluate the stress distribution, displacement behavior, principal stress directions, and energy dissipation capacity under conditions simulating seismic forces. Results revealed a maximum Von Mises stress of 551.3 MPa near the beam-to-column interface and bolt lines. Principal stresses ranged from +403.7 MPa (tension) to –314.2 MPa (compression). Shear stress (S12) values oscillated between +190.5 MPa and –180.6 MPa, confirming significant panel zone shear. Displacement magnitudes peaked at 24.13 mm, reflecting plastic deformation and rotation. The study confirms that finite element simulation is an effective alternative to experimental testing for evaluating complex joint behavior and supports design improvements for seismic resilience in steel structures.
