How is the Tension Web Weld checked?

Example

Design Data
Weld; s = 6 mm
Weld strength; p_w = 220 N/mm2
Web thickness; t_b = 23 mm
Beam design strength; p_y = 345 N/mm2
Tension Zone
Force per unit length; F_Tww = p_y * tb = 7935.0 kN/m
Capacity per unit length; P_Tww = 2.5 * p_w * 0.7 * s = 2310.0 kN/m
Utilisation; F_Tww / P_Tww = 3.435
