Static resistance of laser-made, non-welded T RHS joints estimated using the component method

Resistance of plug & play N type RHS truss connections

“…In Figure 8 to Figure 13 are presented test results and also the theoretical estimations obtained from the decisive components of the joint resistance. Components N1+N2 are adopted from estimation done for T RHS joints [2]. Tests results confirm that it is possible to eliminate the welding in connections between bracing and chord in studied herein N type RHS plug & play joints and reach resistance not less than welded ones.…”

“…4. The resistance of non-welded N RHS joint II generation is similar to face and bottom flange failure for non-welded T type RHS joint [2]. However N type joint of II generation has smaller deformations because of positive influence of the anchor blocks.…”

“…Loads from bracings to the chord are transferred only by squash and shear. The component method which is frequently used for the resistance estimation of the open section joints [1] has been recently used for the RHS truss T joints welded [2] and no welded developed as plug & play [3]. This method is also used for resistance estimation of studied herein plug & play N type RHS joints.…”

Yield load estimation of plug & play N type RHS truss connections

“…Plug & play steel joints [1,6] are the one of the possible answer for the strong need of manufacturers to reduce the cost of steel structures. Moreover, modern techniques introduced by AM, such as: automation of production processes, cutting metals with laser 3D and CNC laser cutter, 3D printers etc are very quick introduced to the process of design and optimization of structure fabrication.…”

“…Loads are transferred only by squash and shear. The component method which is frequently used for the resistance estimation of the open section joints has been recently used for the non-welded T type RHS joints [2,6]. This method is also used for estimation of resistance of studied herein N type RHS joints.…”
