In recent urban developments, the demand for column-free spaces in multi-story buildings has risen due to space constraints, population growth, and aesthetic considerations. To meet these requirements, floating columns are frequently incorporated into building designs. However, these structural elements pose significant risks in seismically active regions, as they disrupt the continuous load transfer path essential for earthquake resilience. This research focuses on the dynamic analysis of high-rise buildings with various irregularities, both with and without floating columns. The study aims to evaluate the seismic performance of these structures by analyzing parameters such as storey displacement, storey drift, and base shear. By using structural analysis software, we model and compare different configurations of high-rise buildings under seismic loads. The findings will provide insights into the impact of floating columns on the structural integrity of high-rise buildings and suggest design improvements for enhanced seismic performance. This research is essential for developing safer building practices in earthquake- prone areas.
