The design concept for the steel part of a composite dowel shear connection

The design concept for the steel part of a composite dowel shear connection is based on a geometric stress concept and it assumes the superposition of individual stress components resulting from longitudinal shearing and bending of a composite section. Analytical transformations of FEM calculation results for critical regions in steel dowels lead to the solution represented by closed interaction curves for the dimensionless shear resis tance of the connection versus the axial resistance of the web.
