ABSTRACT Circular hollow sections (CHS) represent several advantages, such as uniform behaviour in all directions, possibility to obtain composite by concrete infill, hence high strength, stability and good fire resistance. Moreover, their aesthetic appeal has a great potential for the decision maker's attention, be that architect or building owner. However, they are not widely adopted practice due complexity cost of joint details. EU‐RFCS project LASTEICON (Laser Technology Innovative Connections Steel Construction), started on July 2016 [1] proposes simpler solutions with reduced fabrication costs, between CHS columns I beams, making use laser cutting technology (LCT). The primary objective is overcome steel joints let engineers architects exploit outstanding structural properties section profiles. Laser will allow reduction shop time, obtaining higher precision quality fabrication, improving workplace safety reducing amount manual labor while increasing computer‐programmed automation. This paper presents preliminary results obtained Work‐Package 1 ( www.lasteicon.eu ), which consisted study tolerance optimization an efficient I‐beam‐to‐CHS column joints.
