Design Checking for Major Bending & Shear :

Checking for Shear:

Av = t x D = 5.8 x 203.2 = 1179

Shear Capacity, Pv = 0.6 Py Av

= 0.6 x 355 x 1179 / 1000 = 251 kN

>= 35.3 kN OK!

0.6 Pv = 0.6 x 251 = 151 kN

>= 35.3 kN ==> Low shear case

Checking for Bending Moment:

1.2 Py Zx = 1.2 x 355 x 231 / 1000 = 98.4 kNm

Py Zx = 355 x 231 / 1000 = 82.0 kNm

Moment Capacity, Mcx = Py Zx

>= 63.1 kNm OK!

Design Checking for Minor Bending & Shear :

Checking for Shear:

Av = 2T x B = 7.8 x 133 x 2 = 2081

Shear Capacity, Pv = 0.6 Py Av

= 0.6 x 355 x 2081 / 1000 = 443 kN

>= 0.0 kN OK!

0.6 Pv = 0.6 x 443 = 266 kN

Checking for Bending Moment:

1.2 Py Zy = 1.2 x 355 x 46 / 1000 = 19.7 kNm

Py Zy = 355 x 71 / 1000 = 25.2 kNm
