irregular structure
Isaac Kremer/ November 23, 2025/ / 0 comments
A structural system characterized by any of various plan or vertical irregularities, as a soft or weak story, a discontinuous shear wall or diaphragm, or the asymmetrical layout of mass or lateral-force resisting elements. Irregular structures generally require dynamic analysis in order to determine the torsional effects of lateral forces. (Ching, 1995)
