There are three different ways to make HSS.

Thermo-mechanical rolling and the quenching and tempering process, steel with a high construction strength hut guaranteeing also good fabrication properties such as weld-ability was introduced into the construction market Īccording to, S460M & S690Q steel are the most common practiced structural steel material in European construction industry. Some noticeable milestones in terms of structure strength, economy, versatility in architecture, fabrication and erection technology, serviceability and others are introduced in construction industry and these achievements cannot be delivered without implementing steel in structural design. Since first successful incorporation of steel in 19th century to the construction industry, the development of steel construction has brought a revolution in the development of material properties and their method of productions. The elasticity and ductility of steel has made it most reliable and resistant in lateral loads of wind and seismic actions in viewpoint of construction industry.

KeywordsPoisson ratio, welded connection, True stress strain curve, experimental DIC Observing overall experimental results properties and conclusion for each studied joint area has been made and using these results Poisson ratio for each component is determined. DIC results are manipulated using GOM Correlate software and MS-Excel tools.

Stress strain relation has been conducted using miniature tensile testing and for this Digital Image Technology has been incorporated in this experiment. Three different joint areas are taken under consideration namely the base material, filler material and the heat affected zone.
