Structural behaviour of inner set bolted joints in steel tubes under tension

Abstract

In this article, the structural behaviour of a new continuous joint of steel tube under tension is systematically studied. Structural analyses of six typical joints under tension are carried out. The experimental set-up and details of the specimens are introduced, followed by descriptions of the results and experimental observations. Based on the experimental results, the main behavioural patterns are discussed and the salient response characteristics related to stress concentration and capacity are examined. An ideal elastoplastic stress–strain relationship, Mises yield criterion and geometric nonlinear finite element analysis model are established, and a detailed description of the modelling assumptions is presented. A large number of finite element parameters are further analysed. The experimental and numerical findings presented in this article offer direct information on the influence of key bearing capacity properties, such as the plugged length of the cross-gusset, the area of the cross-gusset and the area of the cushion-plate, on the main response characteristics. The results also provide essential data for future analytical and design-oriented studies.

Numerical and theoretical investigation of bolted sleeve connections with rectangular hollow sections

“…In this context, there is an increase in investigations and studies related to the design and behavior of connections in tubular profiles that facilitate the structure assembly processes (Araujo et al, 2016;Luo et al, 2016;Xie et al, 2019;Xing et al, 2020).…”
