Input Data:

Applied Force F = 6 (ton)

Choosen Angle No. 75x75x8

Angle Thickness t = 8 (mm)

Angle Leg Length a = 75 (mm)

Angle eccentricity e = 21.3 (mm)

Member consist of No. of Angles 2 Angles

Gaste Plate Thickness tGP = 1 (cm)

Design Calculation:

F1= F*(a-e)/a 4.30 (ton)

F2=F*e/a 1.70 (ton)

Minimum Weld Requirement Sw min. = 0.4 (cm)

Maximum Weld Requirement = Min. of (t & tGP) Sw max. = 0.8 (cm)

Choosen Sw = Max. of ( Sw min. & Sw max.) Sw (Choosen) = 0.4 (cm)

Lw1 = F1/(No. of Angles)*Sw*(Fall=0.72) Lw1 = 7.46 (cm)

Lw max. = 70 Sw Lw max. = 28 (cm)

Lw min. =Max of( (4*Sw +2*Sw) &(5+2*Sw) Lw min. = 5.8 (cm)

Lw1 (Check )(If Lw1 70*Sw,Lw1+2*Sw,go to note ) 8.26 (cm)

Lw1 min TRUE

Lw1(final) 8.26 (cm)

lw2 =F2/(No. of Angles)*Sw*(Fall=0.72) 2.96 (cm)

lw2 (Check))(If Lw1 70*Sw,Lw1+2*Sw,go to note ) 3.76 (cm)

Lw2 min FALSE (cm)

Lw2(final) 5.8 (cm)

If lw > 70*Sw Fall = B*Fall

B = 1.2-((0.2*Lw1)/(70*Sw)) 1.141
