Solving for the shear strength Vn of a beam with two webs, should the web thickness be doubled because of two webs when performing h/tw?

O divide the shear load by 2. Is this an HSS tube section?

No. The h/tw check is a buckling check, so you should use the thickness of one web.

When figuring the total shear area, you should use two web thicknesses.
