Abstract: The paper deals with the procedure which systematically modifies and identifies the structural parameters, viz. the column stiffness of multistorey structures by using the prior known estimates of the parameters and the corresponding vibration characteristics. For having the accuracy of the identified parameters, an iteration algorithm with the identification procedure is proposed till the parameters converge. Various examples dcmonstrate the reliability and accuracy of the identification process. The effects of a range of experimental (hypothetical) data on thc identified structural parameters for two storeyed frame structures are investigated as an illustration.
