“…A 3D finite element model (FEM) of composite structures can sufficiently evaluate the inelastic behaviour of steel and concrete [36][37][38][39]. However, when considering the non-linear and anisotropic behaviour of timber, failure modes are not readily available.…”

Timber structural members have been widely adopted and used in construction due to their inherent characteristics. The main objective of this work is to assess the performance of timber beams with GFRP pultruded beam reinforcement subjected to flexure. A finite element model (FEM) using ABAQUS FEM software is developed, aiming to provide a benchmark modelling procedure. The modelling method considers the fundamental role of the connections among timber beams, the reinforcing GFRP pultruded profile (adhesive and screw connections), and the grain direction in the timber. To understand the influence of the grain direction, different angles of deviations between the longitudinal direction (along the grain) and the beam axis are considered. The robustness of the developed FEM procedure is validated by the experimental results of timber beams with and without GFRP pultruded reinforcement under flexure. It is demonstrated that the angle of deviation (grain deviation) produces high reductions in the strength of unreinforced timber beams. However, this effect is minimal for GFRP-reinforced timber beams. The experimentally derived benchmark FEM procedure can be used as a computational tool for timber beams with GFRP pultruded reinforcement to capture the capacity, failure mode, and load–displacement response.

“…Stainless steel is an evolving cold-forming material in the construction industry due to its outstanding material properties. Higher chromium content in stainless steel acts as a protective layer against oxidation and corrosion [6][7][8]. The unique characteristics that cold-formed stainless steel sections feature include corrosion resistance, fire and heat resistance, durability, good toughness and fatigue properties, high strength to weight ratio, simple fabrication and handling, and recyclability [4,8].…”

“…Dissanayake et al [19] also conducted FE investigations to assess the shear and elastic shear buckling behaviours of the longitudinally stiffened stainless steel LCBs. Ishqy et al [6] studied the effect of unreinforced circular web openings on the shear behaviour of cold-formed stainless steel LCBs numerically. Moreover, Sonu and Singh [20,21] examined the shear performance of lean duplex stainless steel rectangular hollow beams using FE analyses.…”
