ANALYSIS AND DESIGN OF MULTI STORY BUILDINGS FOR DIFFERENT PLAN IRREGULARITIES

Abstract

Because of their effective structural systems and use of high-strength materials, modern tall buildings are
able to lower their height and become more thin, flexible, and damping-efficient. The residents of these
flexible structures experience discomfort due to their extreme sensitivity to seismic load and wind
stimulation. Thus, a lot of research and studies have been conducted to lessen such an excitation and
enhance tall structures' resistance to earthquake and wind loads. A tall building's architectural design
heavily relies on the early integration of aerodynamic shape, wind engineering considerations, and
structural system choices to minimise the building's reaction to wind excitations. In order to decrease its
dynamic displacement within the bounds of the criteria level for the design wind speed, a tall structure
with an inappropriate form often needs a lot of steel or a unique damping system. Four different shaped
buildings are generally studied for this research work: circular, rectangular, square, and triangular. It
makes sense that choosing the right building shape and making architectural changes are also very
important and effective design approaches to reduce wind and earthquake induced motion by altering the
flow pattern around the building.
The current research concentrated on comparing various building forms, including rectangular, C-shaped,
and T-shaped structures. O-shaped structure ETABS software is used to analyse the shear force, bending
moment, and deflection of L and H shape buildings.
