COMPARATIVE ANALYSIS OF G+5 BUILDING WITH DOG LEGGED AND OPEN WELL STAIR CASES BY USING ETABS SOFTWARE

Abstract

A system of steps called stairs allows one to get from one level to another. An essential functional component of a structure is a staircase. Stairs are becoming more and more popular right now due to their appealing look. A flight of steps that rises to a half step before turning 180 degrees and continuing upward is known as a dog-legged staircase, and it is one of the most basic types of stairs. Due to its sectional elevation look, it is also known as the Dog Legged Staircase. An open well is comparable to a dog-leg stair, with the exception that it separates the two steps. Public buildings often employ the open newel stair, which is a practical stair style.
In this work, response spectrum analysis is used to analyse a G+5 model building. The outcomes, which include tale bending, story shear, story drift, and building In zone V seismic conditions, ETABS software is used to compare the torsion, model frequency, and model stiffness of dog-legged and open well stair cases.
