Assessment of shear wall quantity on seismic performance of high-rise building

Buildings with shear walls are much less likely to sway in the direction of their orientation, reducing the likelihood of structural damage. In addition to providing lateral stiffness, shear walls also prevent roof or floor wobbling. If walls are strategically placed within a structure, they may be able to withstand the lateral forces caused by wind and earthquakes. The investigation of the effects of various floor area ratios on shear walls in a building with an irregular shape is explained in the paper. The primary concern is torsion formation in a structure with an irregular layout. In an irregularly shaped building, the floor area (F/A) ratio of the shear wall is discussed in this essay along with its causes, effects, and potential solutions. In Seismic Zone III, a U-shaped building with 15 stories and medium soil conditions is the subject of the study. Its damping value is 5%. CSI ETABS ver. 19 will be used to accomplish the modeling and analysis. The study will conclude by highlighting the rationale behind selecting a certain test model that demonstrates the lowest levels of story drift, time period, story displacement and base shear. This test model has a varied percent shear wall (impact of a variable floor area ratio of shear wall).
