Dynamic Analysis and Design of RCC Framed Irregular Structure” Using ETABS & RCDC

Abstract

A building that lacks symmetry and has discontinuity in geometry, mass, or load resisting elements is called irregular. These irregularities may cause interruption of force flow and stress concentrations.

Horizontal irregularities which refer to asymmetrical plan shapes (e.g. L, T, U, F) or discontinuities in the horizontal resisting elements such as cut-outs, large openings, re-entrant corners and other abrupt changes resulting in torsion, diaphragm deformations and stress concentration.
