Seismic Assessment of Multistorey building of plan irregularity with varying A/L ratio (Re-entrants corners)

Abstract Buildings with re-entrant corners are used when maximum utilization is done over minimum available space. These come under the plan irregularities of structures. Plan irregularity (or) Vertical makes vulnerable seismic loading. Structural an important factor in that structure’s performance structure. This study aims to gain behaviour building L-shape floor by checking response demands been measured varying A/L ratios. The includes top displacement, interstory drift, Story Stiffness, and base shear. consists 5 models ratios 3 sub-divided various positions shear wall (i.e.) a model without wall, at centre, periphery. 15 made for clear effective position analysed ETABS using Equivalent static method (ESL) Response Spectrum (RS) methods. results prove lesser ratio satisfies analysis even excluding lift RCC whereas increases only provided Thus, economical found demand As more must be regular configuration possess significant resistance.
