Abstract

A criterion is presented to make decisions concerning the optimal location of accelerometers for the identification of uncertain structural systems subjected to earthquake ground motions modeled as stochastic processes. A measure of goodness of an instrumentation scheme is defined in terms of a Bayesian loss function which is related to the so-called Fisher information matrix. The criterion to determine the optimum instrumentation alternative is then to select the one which minimizes the expected value of the loss function. It is applied to the case of a shear building model and the effect of noise and duration of recordings on the optimal instrumentation is assessed. 1. Introduction A few researchers have studied the problem of optimizing the location of recording instruments for identification pu
