The Model of Bounds on Seismic Responses

Abstract:

Seismic excitation of linearly elastic structures is dealt with in the paper. It is well known that dynamical structural response is very sensitive to random fluctuations of the excitation; the consequence is that the identification of the forcing function on the basis of a few global parameters does not allow to predict exhaustively stresses in seismically excited structures. In the paper, a convex model is established to treat uncertainty associated with the details of the excitation. In order to set bounds on the response parameters of a SDOF system, assuming that only rough information is available for expected earthquakes at a given site. In particular, we assume that the maximum expected energy of the acclerogram, and the maximum distance of its power spectrum from the target spectrum, typical for the site under construction, are specified.
