REVIEW-DYNAMIC ANALYSIS ON MULTI-STOREYED BUILDING WITH & WITHOUT FLOATING COLUMN

Abstract

The increasing demand for architectural flexibility in modern multi-storeyed buildings has led to the widespread adoption of
floating columns. While these structural elements enable functional and aesthetic enhancements by creating open spaces in lower floors, they also introduce significant challenges to the overall stability and seismic resilience of buildings. This review delves into the dynamic analysis of buildings with and without floating columns, providing a comprehensive assessment of their behavior under dynamic loads such as earthquakes. The paper explores various analytical methods, including modal analysis, response spectrum analysis, and time historyanalysis, to evaluate the structural implications of floating columns. Key findings from existing studies indicate that buildings with floating columns experience higher inter-storey drifts, increased base shear, and amplified stress concentrations, which compromise their seismic performance. In contrast, structures without floating columns demonstrate superior stability, uniform load distribution, and enhanced dynamic response
