Non-Linear Behaviour of Continuous Steel-Concrete Composite Beams
Continuous composite beams are affected by negative bending moments at the internal supports; thus tensile stresses arise in the concrete slab. Cracks in the concrete slab and slippage between concrete and steel component make the structural response very complex in the hogging moment regions. Thus behaviour results from many non linear phenomena involving the reinforced concrete and the steel components, and also very localised effects due to bond of the reinforcing bars and shear connection. Recent developments in the field of modelling of such beams are presented and a theoretical model able to take account of partial interaction and tension stiffening effect is discussed.
