SEISMIC BEHAVIOUR OF MULTISTOREY RC BUILDING WITH FLOATING COLUMNS

  • Unique Paper ID: 193271
  • PageNo: 4374-4385
  • Abstract:
  • The growing demand for open and flexible architectural spaces in high-rise buildings has led to the widespread adoption of floating columns, particularly at lower storey levels for parking areas, lobbies, and commercial spaces. This study evaluates the seismic response of a 30-storey (G+30) building positioned on sloping terrain with inclinations of 5°, 10°, 15°, and 20°, focusing on the influence of floating column termination height (3rd, 6th, and 12th levels) and the effectiveness of flag shear wall placement. Nonlinear dynamic analysis and modal evaluation were performed to quantify top-storey displacement, inter-storey drift, lateral stiffness, and fundamental time period in both principal directions.
