Unlock the reasoning, formula path and code-linked notes inside your student dashboard.
Design strength per unit length = fu/(√3 × γmw) × throat = 410/(√3 × 1.25) × 0.707×8 = 410/(2.165) × 5.656 = 189.4 × 5.656 ≈ 1071 N/mm. Total: 1071 × 150/1000 ≈ 160.7 kN. Key: throat = 0.707s, γmw = 1.25 for shop weld, fu = 410 MPa for Fe410.
