This paper investigates the effect of the temperature variation on the natural frequency of Canton Tower, applying geometric modelling and finite element analysis (FEA) for a deep exploration of this subject. By simulating the vibrational characteristics of Canton Tower under different temperature conditions, the paper analyse how temperature variation affect its natural frequency. The finding reveals that temperature changes lead to variations in the material’s elastic modulus and thus influence the tower’s vibrational properties. Specifically, as temperature increases, the natural frequency decreases, and vice versa. These findings underline the importance of considering temperature effects in the structural design and safety monitoring of the Canton Tower, as well as other similar high-rise structures, to ensure their long-term stability and performance under varying environmental conditions.
