Improved FE model to simulate interfacial bond-slip behavior in composite beams under cyclic loadings
A model for analyzing partially composite beams under cyclic loadings is proposed. Hysteretic material models are used in the nonlinear formulation of a beam element. Correlation studies between numerical results and experimental studies are conducted. The numerical analysis through the proposed model shows a clear pinching shape. The analysis assuming fully composite action represents an overestimated behavior.
