There has been growing recognition of the need for a more explicit consideration of material degradation effects in structural design. This article presents a procedure for the design of metal fasteners used in exposed timber structures that is suitable for use in modern reliability-based engineering design codes. The procedure is focused on the computation of the effective loss of structural section that is related to a specified service life. The fasteners are considered to be subjected to two types of corrosion: (1) the corrosion of exposed parts of the fasteners, where the corrosive agents are airborne salinity and pollution agents and (2) the corrosion of parts of the fasteners embedded..View full abstract
