8 - 27 Worked Example 5: Web Resistance 1 of 2 Made by CZT Date 02/2010 Calculation sheet Checked by ENM Date 02/2010 1. Web Resistance This example presents the method used in the member resistance calculator for calculating the web resistance and the shear resistance, adopting the recommended values of the EN 1993-1-5 and EN 1993-1-1. Section: IPE 500 Steel grade: S355 c = 10 mm s s = 100 mm 1.1. Shear resistance In the absence of torsion, the shear plastic resistance depends on the shear area, which is given by: A v = A – 2 b t f + ( t w + 2 r ) t f A v = 11600 – 2 × 200 × 16 + (10,2 + 2 × 21) × 16 = 6035 mm 2 EN 1993-1-1 § 6.2.6 (3) V pl,Rd = 3 M0 v y  A f = 3 1,0 355 10 6035 3     = 1237 kN V pl,Rd = 1237 kN EN 1993-1-1 § 6.2.6 (2) 1.2.
