✦ Synopsis

An analytical description of the behaviour of a connection has to cover all sources of deformabilities, local yielding, local instabilities, etc. Due to the multitude of in¯uencing parameters, a macroscopic inspection of a complex connection Ð by subdividing it into components Ð has proved to be most appropriate. This is the approach recently proposed by the Eurocode 3. One of the basic components is the equivalent T-stub, which adequately models several parts of a connection: column ¯ange in bending, end plate in bending and ¯ange cleat in bending. Reliability techniques combined with non-linear analysis of structures have been applied to interpret the eects of parameter variability on the T-stub behaviour. Simpli®ed safety rules are derived from this probabilistic high-level approach.
