Review-Analysis and Design of Multistorey Building by Curtailment of Shear Wall

Abstract

Shear walls are a critical structural element in high-rise buildings, providing resistance against lateral forces such as wind and earthquakes. However, the conventional design approach often extends shear walls continuously throughout the building height, which may lead to material overuse and unnecessary increase in construction cost. Curtailment of shear walls, i.e., strategic reduction in wall length or discontinuation beyond certain floors, offers potential optimization without compromising safety and serviceability. This review examines existing research and case studies related to shear wall curtailment in multi-storey structures. The focus lies on analyzing structural behavior, displacement control, base shear distribution, and cost efficiency under varying seismic zones. Various analytical methods, including finite element analysis in ETABS, STAAD Pro, and ANSYS, are reviewed. The study concludes that optimized curtailment can maintain performance while improving cost-effectiveness, provided careful evaluation of seismic demand, building height, and stiffness distribution undertaken.
