Laser Technology for Innovative Connections in Steel Construction

Short description

Circular hollow sections represent several advantages, such as uniform behaviour in all directions, possibility to obtain composite behaviour by concrete infill, hence high strength, stability and good fire resistance. Moreover, their aesthetic appeal is a great potential for decision maker’s (architect, building owner) attention. However, they are not widely adopted in practice due to the complexity and high cost of their joint details. LASTEICON proposes simpler joint solutions with reduced fabrication costs, to be adopted between CHS columns and I beams, making use of laser cutting technology (LCT). Extendibility of the solution to other construction applications will be also investigated.
