Title A.4 Worked Example – Simply supported, primary composite beam 2 of 13 4 – 82 The beam is an I-rolled profile in bending about the major axis. This example includes:  the classification of the cross-section  the calculation of the effective width of the concrete flange  the calculation of the shear resistance of a headed stud  the calculation of the degree of shear connection  the calculation of the bending resistance  the calculation of the shear resistance  the calculation of the longitudinal shear resistance of the slab  the calculation of the deflection at serviceability limit state. This example does not include any shear buckling verification of the web. 4.1. Partial factors   G = 1,35 (permanent loads)   Q = 1,50 (variable loads)   M0 = 1,0   M1 = 1,0   V = 1,25   C = 1,5 EN 1990 EN 1993-1-1, § 6.1 (1) EN 1994-1-1, § 6.6.3.1 EN 1992-1-1 4.2.
