Part 4: Detailed Design 4 – 33 End Bending criterion verified ? Calculate internal forces and moments Verification of bending resistance, see Figure 5.7 Span Length Load combination Start V Ed , M Ed Choose beam section, concrete parameters, connectors Calculate Effective width of concrete flange EN 1994 1-1 § 5.4.1.2 Calculate connectors design resistance EN 1994 1-1 § 6.6.4 P Rd Cross section data Steel grade Connectors data b eff V Rd Yes V Ed ≤ V Rd No No Verification of longitudinal shear resistance of the slab, see Figure 5.9 Longitudinal shear criteria verified ? Yes Yes No Calculate Shear Resistance, see Figure 5.8 When the beam is not fully propped during construction, it has also to be checked without the contribution of the concrete slab EN 1994 1-1 § 6.6.6.2 EN 1994 1-1 § 6.6.3 Note that rectangular boxes with heavy surrounds are references to detailed sub-processes in Figure 5.7 to Figure 5.9.
