ABSTRACT
This paper presents a study on the variation of ductility capacity and demand in steel members. It was found that the ductility capacities of steel members vary significantly with coefficients of variation reaching 50–100% and are greatly influenced by the strain-hardening characteristics of the steel material. Variation of ductility demand caused by variation of member strength was examined using Monte Carlo simulation and an analytic procedure proposed by the writer. This variation was found to be rather significant. Subsequent discussion pursues the possibility of increasing structural safety by raising the strength capacity.
