STUDY ON G+6 BUILDING WITH DIFFERENT PLAN IRREGULARITIES BY STAAD PRO SOFTWARE

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 employed STAAD Pro V8i software to compare the shear force, bending moment, and deflection of buildings of the following shapes: rectangular, T-shaped, H-shaped, and O-shaped.
