: This research adds to the literature through a complete finite element analysis (FEA) of an RC chimney subjected to the combined action of wind load and temperature variation, in accordance with the specifications of IS 4998:2015. In contrast to earlier studies where simplified analytical procedures are emphasized, this work uses a fine mesh convergence study and time step determination to achieve numerical accuracy. The verification of results by hand calculations and IS code compliance also increases the reliability of the study. The results affirm that the RC chimney is within acceptable stress and deflection limits, providing useful information regarding the design and safety evaluation of industrial chimneys exposed to severe environmental conditions. This study provides a basis for future research involving soil-structure interaction and experimental verification, thus enhancing the understanding of chimney behavior under actual conditions.
