The aim of the article is to propose a new method for assessing the flexible joints of welded trusses with chords made of C-sections and braces made of rectangular hollow sections. In thismethod, the capacity of the welds is determined depending on the value of the axial force, taking into account the effective lengths of the fillet welds. As shown in the article, in such connections, the use of thin fillet welds with a thickness matched to the member's load is twice cheaper than the use of solid butt welds. Additionally, the life cycle analysis performed showed that the use of thinner fillet welds could reduce the overall environmental impact of the welded joint by 73% in terms of greenhouse gas emissions and 70% in terms of non-renewable primary energy consumption.
