Abstract:
Estimating the nonlinear behavior of sturctures, always have been one of the main concerns of civil engineers. One of the most recent methods for estimating behavior of structures is MIDA technique. It is a procedure that in some levels, substituted for IDA. Although this method presents the approximate results, high accuracy, fastness and inexpensive procedure made this manner to an efficient method. Indeed, this method has been presented to be exerted instead of exact IDA method which is too complicated and prolix. Up to now, no one has used this method for structures incorporating soil-structure interaction. In theMIDA manner, there is no dynamic analysis of whole structure. Therefore, it could be interpreted that this method cannot be used for structures incorporating SSI. In this article, it is intended to represent an approach to use MIDA method for structures, which damped by additional viscoelastic damping and incorporating SSI. The results show appropriate accuracy of proposed technique in applying MIDA method for these kinds of structure
