Finite-element model of a tall reinforced concrete chimney

First vibration mode visualization of a tall chimney

Published structural research

Wind, seismic and dynamic response of a 150 m RCC chimney

Design of Tall Chimney for Thermal Power Plant, authored by Karan Dhall and published in IJRASET, Volume 8, Issue V, May 2020, pages 553-571.

The paper studies a 150 m single-flue RCC chimney through finite-element modal analysis and the assessment of along-wind and across-wind response. This research perspective informs practical decisions on dynamics, stability, serviceability and load-sensitive tall structures.
