Abstract
In this paper, using the concept of the equivalent external force, we develop a linear algorithm to identify dynamic parameters of structural system. An identification algorithm is also developed for the case that the measurements of the structural responses are limited at several floors. In proposed identification algorithm, we first estimate the equivalent external force at unobserved portions of structural system, and then identify dynamic parameters of structural system using the recursive least-square method. The efficiency of our proposed algorithm is verified through two numerical examples.
