The present work deals with the active vibration control of isotropic and laminated composite box type structure under thermal environment using finite element method. Plate finite element is developed based on the displacement field proposed by Ramkumar et al. [4] has been considered for the present study. The effect of temperature and control gain on natural frequency and damping of the system are investigated for different boundary conditions by using active feedback control. Results are presented for frequencies and loss factor with different column thickness and lengths. In addition, dynamic characteristics of box structure is calculated by using plate finite element are compared with 3D beam finite elements for investigating the nature of mode behavior. Characteristics of loss factor and frequency near the buckling temperature are also discussed. © Research India Publications.
