A validated finite element model has been used to perform a comprehensive set of parametric studies to investigate the effects of different design parameters on the connected plate behavior, including initial stiffness, ultimate resistance and maximum deformation at the ultimate resistance.
The validated finite element model was then used to perform a comprehensive set of parametric studies to investigate the effects of different design parameters on the connected plate behaviour, including initial stiffness, ultimate resistance and maximum deformation at the ultimate resistance.
The initial stiffness, ultimate tensile strength, demountability as well as the post-peak behaviour is investigated.
Results indicated that the doubler plate can significantly increase the initial stiffness, ultimate capacity, and considerably improve failure modes.
Strengthening of pre-cracked beams showed increases in the initial stiffness, ultimate load, and deflection, compared to the equivalent control beam.
The FE model is shown to accurately replicate the experimentally determined, initial stiffness, ultimate resistance, overall moment-rotation response and observed failure modes.
The effects of the shank diameter and aspect ratio on failure modes, initial stiffness, ultimate strength and ductility of the shear connectors are investigated through push-out tests.
Results indicated that the doubler plate can significantly enhance the initial stiffness, ultimate capacity, and considerably improve failure patterns of T- and Y-joints under IPB load.
The results of finite element analyses are compared with simplified analysis to enable a better understanding of the distribution of forces and deformations at the initial and ultimate stages.
