“…• Unions by fitting tubes in continuity is called sleeve connection. In this case, the examples in the literature have used through screws in round tubes [5] or blind screws in square tubes [6]. This last reference considers moments at the joint, while the previous ones only take axial forces into account.…”

The present piece of research studies partial sleeve joints between similar rectangular tubes, involving bolts under shear as joining means. These are connections between two rectangular hollow sections that can be fitted one in another just by adequately cutting some faces and then bolting. For these elements, the use of self‐drilling screws is evaluated here. These connections could be removable and reusable in some cases, providing more sustainability. They also present semi‐rigid behaviour, which leads to weight saving structures and makes them ideal in many situations for structures like greenhouses or other light portal frames.The structural joints following this typology can be planned as beam‐column, ridge, or even column‐base plate joints. This paper is focused on the initial experimental results of the first two cases under bending moments, comparing them with some simplified analytical assumptions for the strength and the stiffness. These calculations are based on eccentric bolted connections with in‐plane moments but considering some particularities of these joints and joining means (self‐drilling screws).

“…This connection is composed of outer tubes connected by an inner tube and bolts. Ini-tially, the sleeve connection was studied for circular hollow sections (CHS) by Amparo (2014), Amparo et al (2015), Roquete et al (2017), Roquete (2018), Oliveira (2019), Oliveira et al (2020), Roquete et al (2021) and Roquete et al (2022). Figure 1 shows an example of sleeve connection with CHS evaluated by Roquete (2018).…”

“…The contact pair CONTA175 and TARGE170 was used to represent the contact between the bolts and the transverse section of the RHS tube in the holes. The same finite elements were used by Oliveira et al (2020), Roquete et al (2021) and Roquete et al (2022) for analysis of bolted sleeve connections with CHS.…”

This article presents a theoretical and numerical study of bolted sleeve connections with rectangular hollow sections (RHS) under axial tension and compression. The geometric form of a hollow section provides resistance for high axial loads, torsion and combines effects, spreading its utilization in truss systems. In this context, the sleeve connections proposed explore these characteristics of RHS and offer an attractive aesthetic appearance for the continuity of elements. The bolted sleeve connection with RHS is formed by two outer tubes connected by an inner tube and staggered bolts. Herein, a parametric study was developed for identification of the failure modes in the connection. Finite element models with different geometric parameters and number of bolts were created in commercial software. The width, depth and thickness of RHS tubes and diameter of bolts were variated. In the theoretical/numerical/ parametric results, the yielding gross section failure, the fracture through the effective net area failure and the bearing failure were observed. These failure modes occurred in both outer and inner tubes. The load results were compared to determine the resistance capacity of sleeve connections. The theoretical formulations were evaluated for representation of the ultimate load of the failure modes.
