The scope of BS EN 1993 is wider than most of the other design Eurocodes due to the diversity of steel structures. Therefore this Eurocode covers both bolted and welded joints, and the possible slenderness of construction.
The real differences when compared to existing British Standards are that the Eurocode brings new methods into the scope. For example, the design of semi-rigid joints in buildings is explained, and more advanced methods of design for cold-formed steelwork are included. The rules for shell and for the design of piles, sheet piling and silos are new, and rules for stainless steel appear for the first time.
BS EN 1993 covers common rules, fire design, bridges, buildings, tanks, silos, pipelined piling, crane supported structures, chimneys, towers and masts etc
