Combination of steel and concrete is inevitable for composite beams to deliver high performance. Contact interface between steel and concrete plays one of the most crucial roles for numerical performance evaluation of composite beams by nonlinear finite element analysis. However, difference in scale between composite beams and shear connectors makes the contact analysis of composite beams impossible because of the complexity of the numerical models required. In this paper, we develop a performance evaluation method for composite beams based on the homogenization method utilizing a representative volume element including shear connectors and contact interface.
Key Words : contact analysis, homogeneization method, composite beam
