Eurocode design of composite concrete beams
Original language description
concrete beams made of prefabricated prestressed or non-prestressed element and cast-in-place reinforced Composite concrete slab became very popular in present-day civil engineering practice. Two concrete composite parts of beam are cast at different times. Different moduli of elasticity, consecutive load application, and differential creep and shrinkage cause unequal strains and stresses in two adjacent fibers of construction joint. The requirement is to ensure that both parts act fully compositely, because the bending and shear designs of composite members are based on this assumption. The objective of the paper is to review the methods for the calculation of shear stresses in construction joint, and to evaluate the influence of different age of twoconcrete composite parts on the level of shear stresses. It was observed that differential shrinkage of concrete components can significantly affect the stress distribution. Numerical studies were performed based on real-life examples of
