The following work deals with improving the vibration model of structures obtained by the differential quadrature element method (DQEM). To this end, first, an initial model of the structure is constructed using the DQEM in which the values of several physical parameters are unknown. Then, an optimization problem is defined to find the optimum values of the design parameters. To solve the optimization problem, a robust evolutionary algorithm, namely the artificial bee colony (ABC), is utilized. To verify the effectiveness of presented approach, the experimental data obtained from the modal testing of a plane frame are utilized to update the DQEM model. The results show that the updating process is successfully performed utilizing ABC, and the updated DQEM model better represents the vibration behavior of the real structure.
