Analysis of Soft Storey Building with Different Percentages of Openings in Shear Walls by Using Etabs Software

Abstract

Concrete building heights have expanded in the last few decades as the most common structural forms have been shear walls and tube constructions. This suggests that the structural behavior of the latter is more sophisticated than that of earlier RC skyscrapers. As a result, learning more about the structural systems and associated behavior of such buildings would be fascinating. This research will examine the structural characteristics of one of the world's tallest reinforced concrete structures, situated within the seismic zone of Hyderabad. Because the construction uses a shear wall system with uneven apertures, the shear walls, coupling beams, and other structural elements may react abnormally when subjected to lateral and gravitational pressures.

Buildings typically have shear wall apertures for ventilation shafts, windows, and doors, among other functional purposes. Depending on architectural and practical factors, apertures can have varying sizes and placements. Most apartment buildings do not take into account the potential effects on the building's structural behavior that the location and amount of shear wall apertures may have. For this reason, ETABS V 9.7.4 is being used to conduct a reaction spectrum analysis on a 15-story frame wall building.  The models with 15%, 18%, and 28% extra gaps in their shear walls are examined, going down from the highest to the lowest values. This study looks into the relationship between the location of an opening in a shear wall and the drift, shear, and moment values.
