Please answer on the image attached Thank you
Refer to the figure. The butt connection shows 8-22mm diameter A325 bolts spaces as follows:
=
S₁ = 60mm; S₂ 100mm; S3 = 60mm; S4 = 120mm
Thickness of plates (top and bottom): t₁ = 12 mm
Thickness of plates (middle): t₂ = 16 mm
Steel strength and stresses are:
Yield strength, Fy = 250 MPa
Ultimate strength, Fu = 400 MPa
Allowable tensile stress on the gross area= 0.6Fy
Allowable tensile stress on the net area= 0.5Fu
Bearing stress on projected area, Fp= 1.5Fu
Allowable bolt shear stress, Fv=130 MPa
