The use of tubular joints (TJs) is evident, although they are commonly utilized in different
areas, such as buildings, bridges, offshore structures, and renewable energy structures …

In the present study, a total of 360 FE analyses were carried out on tubular X-joints
strengthened with collar plates under brace tension under laboratory testing conditions (20° …

Exposure to load and offshore environment degrades the load-bearing capacity of tubular
joints, necessitating reinforcement of these joints. Reinforcement is sometimes required for …

Highlights•A total of 360 FE models was generated to provide the ultimate strength values in
tubular T/Y-joints with collar plates at room and different elevated temperatures.•The …

In this paper, the results of performing finite element (FE) analysis on 360 tubular X-joints
reinforced with collar plates have been used to propose a probability distribution model for …

This paper presents the failure pattern, ultimate static strength and detailed behavior of steel
tubular T-joints strengthened by fiber reinforced polymer (FRP) obtained from numerical …

In the companion paper, the results of 12 tests on reinforced and unreinforced tubular T-
joints subjected to axial brace loading were presented. The current study reports the finite …

This paper focuses on identifying the most appropriate probability distributions for
characterizing the ultimate strength of FRP-strengthened X-shaped tubular joints under axial …

In the present paper, the Local Joint Flexibility (LJF) of tubular T/Y-joints retrofitted with Glass
Fiber Reinforced Polymer (GFRP) under IPB moment is studied and discussed. For this aim …

The paper presents a comprehensive test program on collar plate reinforced CHS T-joints
under different preload conditions, in order to investigate the effect of preload and welding …
