Parametric study and formula for SCFs of FRP-strengthened CHS T/Y-joints under out-of-plane bending load

Hossein Nassiraei et al.

Summary: This paper investigates stress concentration factors in tubular T/Y-connections strengthened with fiber reinforced polymer (FRP) under OPB, showing that FRP strengthening can significantly reduce the SCF. The increase in the number of FRP layers and the elastic modulus of FRP along the fibers further decrease the SCF ratios.

Local joint flexibility of tubular T/Y-joints retrofitted with GFRP under in-plane bending moment

Hossein Nassiraei et al.

Summary: This study focuses on the Local Joint Flexibility (LJF) of tubular T/Y-joints retrofitted with Glass Fiber Reinforced Polymer (GFRP) under IPB moment. A finite element (FE) model was used to evaluate the impact of FRP sheet properties on the LJF, showing that increasing the number of FRP sheets leads to a significant decrease in LJF, while the orientation of the sheets has negligible effect. The study also derived a parametric equation for determining the LJF of retrofitted joints and checked it against acceptance criteria.

Static capacity of tubular X-joints reinforced with fiber reinforced polymer subjected to compressive load

Hossein Nassiraei et al.

Summary: The study investigates the performance of tubular X-joints reinforced with FRP under compressive load using finite element models, showing that FRP can significantly enhance the stiffness and ultimate capacity. A theoretical formula based on the yield body model is proposed to predict the ultimate strength of X-joints with FRP, which is in accordance with the acceptance criteria of the UK Department of Energy.
