Developments in the design, fabrication and erection of steel structures together with
the introduction of new high performance materials have lead to significant changes in the design,
buildability and performance of steel structures and in particular their connections. Early steel
structures used riveted connections but following technological developments shop welded and site
bolted connections are now common place. The introduction of high strength steels has increased the
types and grades of bolt available to the designer. The range of bolts now includes ordinary strength
steels bolts such as grades 4.5, 4.6 and 5.6 and high strength steel bolts such as grades 8.8, 10.9 and
12.9. Developments in automatic fabrication have seen a move away from manually produced
drawings and setting out to sophisticated design software directly connected to numerically controlled
machines for laser cutting, punching and drilling. The quality of welding has also improved with the
introduction of continuous casting of steel and welding robots.
