Parametric Numerical Study of Welded Aluminium Beam-to-Column Joints

Beam-to-column joints are one of the most common types in metal structures. In design load-bearing aluminium structures, welding, as a joining method, is often avoided because localised degradation mechanical properties heat-affected zone (HAZ). However, recent experimental studies on extent and strength HAZ show significant difference compared to very conservative rules when modern welding techniques used. Therefore, numerical study conducted this paper addresses influence behaviour welded beam-to-column joint. Parametric analyses were performed varying alloys, reduced HAZ, different definitions extent. The obtained results that highest stress concentration occurs at connection between top beam flange column flange, resulting plastic softening region. Different joint capacities observed by HAZ. A detailed overview models well moment–rotation curves some not assumed standards considered.
