Abstract

A previous dynamic identification technique based on the use of Restricted Potential Models (RPM) is modified and used for the identification in the time domain of civil structures under base lateral loads. RPM are used because they make one able to predict the behaviour of a large number of systems that can be found in practical cases. Unfortunately, they have the defect to be characterized by equally distributed velocities in a each degree of freedom by the probabilistic point of view against the real characteristics of civil structures. Through the paper how can be solved this problem is discussed and how the identification technique based on these models can be effectively used for identification of civil structures. Finally an application is shown.
