Impact of Solid Segment Weak‑Beam Configuration Arrangement on the Seismic Delicacy of Rc Outline Structures

Abstract

Incremental dynamic analyses are conducted for a suite of low- and mid-upward thrust strengthened-concrete unique moment-resisting frame buildings. Buildings non-conforming and conforming to the robust-column weak-beam (SCWB) design criterion are considered. These homes are designed for the 2 most excessive seismic zones in India (i.E., area IV and quarter V) following the provisions of Indian Standards. It is observed that buildings non-conforming to the SCWB layout criterion result in an undesirable column failure fall apart mechanism. Although yielding of columns can not be avoided, even for homes conforming to a SCWB ratio of one.4, the found disintegrate mechanism changes to a beam failure mechanism. This exchange in disintegrate mechanism ends in a  extensive growth inside the building’s worldwide ductility ability, and thereby in collapse ability. The fragility analysis study of the taken into consideration homes indicates that considering the SCWB design criterion results in a significant reduction in collapse opportunity, mainly in the case of mid-rise homes.
