Non-stationary property in frequency content of horizontal ground motion vectors
The non-stationary properties of the strong ground motions are considered to have dominant influence on the dynamic response of structures. In this article, a new method is proposed to study the instantaneous frequency by constructing analytic signals with two orthogonal horizontal components of gro...
