This chapter is concerned with human error as it affects the products of the structural engineering profession and the construction industry. Yet is must be said at the outset that the structural engineering industry has an excellent record in achieving structural safety and structural serviceability. The risk of death as a result of structural failure while a structure is in use is very low, as indicated in Table 10-1. The statistics for structural failure therein refer to buildings, bridges, etc., but even extending the definition to the structural components of aircraft, trains, aerospace vehicles, and motor cars will not change the conclusions significantly. It is clear that only very occasionally do significant structural failures occur. Why, then, should we be concerned about structural reliability and in particular the influence of human error on structural reliability? |
