3. Shear Strength for PL 200x20
5 Minutes Structure

4. Example Details
Material – G40.21 350W
A325 22mm Diameter
Holes are Punched.
5 Minutes Structure

5. Tensile Resistance Tr = φu*Ane *Fu
Here, φu = 0.75
Ane = An = 200*20 – 3*(22+4)*20
= 2440 mm^2
Fu = 450 MPa
Tr = 0.75*2440*450 = 823500 N = 823.5 KN

Path 1 – Red
Path 2 – Blue
(Staggered)

7. Tensile Resistance Tr = φu*Ane *Fu
Here, φu = 0.75
Ane = An = 200*20 – (22+4)*20*2
= 2960 mm^2
Fu = 450 MPa
Tr = 0.75*2960*450 = 999 KN
5 Minutes Structure
Path 1 - Red

8. Pitch and Gauge
Pitch – 80 mm (Greater than 2.7d)
Gauge - 80 mm (Greater than 2.7d)

9. Tensile Resistance Tr = φu*Ane *Fu
Here, φu = 0.75
An = 200*20 – 3*(22+4)*20 + (

4∗80
∗ 20 ∗ 2 = 3240 mm^2
Ane = U*An = 0.85*3240 = 2754 mm^2
Fu = 450 MPa
Tr = 0.75*2754*450 = 929.475 KN

10. Governing Tensile Resistance
Path 1 - Tensile Resistance = 999 KN
Path 2 - Tensile Resistance = 929.475 KN (Govern)
The Lower one will govern for Tensile Resistance
