|| Irregularities in the structure are crucial factors in screening structural vulnerability under extreme loadings.
Numerical analyses were carried out considering wind and seismic loadings for four structures with discrete irregularity:
continuous and discontinuous beams with varied story levels, and L-shaped irregular buildings. Structural responses such
as maximum displacements, bending moments, axial forces, torsions, and story drifts are evaluated as per the criteria and
limits defined by ACI 318. The outcomes indicate that the frame system with beam discontinuity on the upper half of the
height exhibits the best structural performance. The results also indicate that the asymmetrical design of the L-shaped
model makes it more susceptible to damage when subjected to strong lateral loading conditions.
