Non-linear truss reliability by monte carlo sampling

The problem to calculate trusses reliability under random loading is approached, assuming that single members in the truss exhibit non-linear elastic behaviour for uniaxial state of stress. Usual monte carlo methods require that non-linear response be evaluated under any sample loading generated by the simulation techniques. In the paper, linearization of the system is considered, and relations between safe domains in the load space both for linearized real structures are investigated. It is next proved that, by using a suitable selective sampling technique, errors on the failure probability induced by linearization are implicitly corrected. Finally, numerical results and comparisons are considered in order to judge the effectiveness of the proposed method (a).
