Abstract: Sophisticated computer programs for the determination of the effects of instability on the inelastic stress resultants in steel structures will appear to be 'black boxes' to designers. They will therefore require validation before they can be accepted as legitimate tools in the design of steel structures. This paper discusses the problem of validation, and makes preliminary proposals to establish a method of validation which includes a series of representative problems whose solutions can be used to benchmark computer programs, which should be provided in the description of the basis and attributes of the computer programs.
