Abstract This paper presents the development of an effective luau thank you cards numerical formulation for the analysis of steel-concrete composite structures considering geometric and materials nonlinear effects.Thus, a methodology based on Refined Plastic Hinge Method (RPHM) was developed and the stiffness parameters were obtained by homogenization of cross-section.The evaluation of structural elements strength is done 6-0 igora vibrance through the Strain Compatibility Method (SCM).The Newton-Raphson Method with path-following strategies is adopted to solve nonlinear global and local (in cross-section level) equations.

The results are compared with experimental and numerical database presents in literature and a good accuracy is observed in composite cross sections, composite columns, and composite portal frames.
