Abstract: In this paper, it is shown that the input process in the nonstationary case must be defined as a complex process, i.e., as the product of an analytic random stationary process by a deterministic shaping function. Defining ...

Abstract: In the framework of modal analysis the dynamic correction method is applied to evaluate the response of elastic perfectly plastic systems having numerous degrees of freedom. According to this method, the nodal structural ...

Abstract: In the dynamical analysis structural modifications often appear for many reasons such as designer structural alterations, and discrepancies between predicted and measured properties of the structures. Furthermore, sometimes ...

Abstract: A semi‐empirical method for the evaluation of the statistical characteristics of the mean, variance and the maximum response peak of a single degree of freedom linear system under seismic action is presented. The nonstationary ...

Abstract: Two methods able to capture with different levels of accuracy the discontinuities in the bending moment and shear force laws in the dynamic analysis of continuous structures subject to a moving ...

Abstract: In earthquake engineering, recorded accelerograms must be critically analyzed to predict the seismic behavior of structures under future earthquakes. Recent studies have highlighted that, in addition to amplitude, the ...
