Abstract :
Structural uncertainties given by intervals are studied within a finite element formulation to determine sharp bounds for the quantities of displacement response. In order to obtain the sharp solution as much as possible, two approaches are proposed here: the interval finite element approach and the optimization approach in which both of displacement and structural uncertainties are variables. Those are applied to the analysis of simple truss structure models with uncertainties of nodal coordinates
