Abstract
This paper deals with seismic excitation of linearly elastic structures. 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 accelerogram, and the maximum 'distance' of its power spectrum from the target spectrum, typical for the site under construction, are specified. © 1998 John Wiley & Sons, Ltd.
