This would imply that no weld would be needed at the center, yet this is the section where having the entire cross-section engaged in bending is most critical. It is actually at a maximum with the maximum moment.

The entire section resists the moment if the welds are adequate to transfer the shear. I remember a demonstration in statics class where a load is applied to a stack of unattached plates and to a stack of plates attached together. Maybe I am misunderstanding my texts. How is the horizontal shear calculated? I is the horizontal shear due to vertical shear forces on the beam. Horizontal shear forces due result from vertical.

What is the horizontal shear force in the center of the beam I described in the original posti. Your explanation seems perfectly logical and agrees with what the texts say. The horizontal shear stresses are a result of the differential moment. If you think about a simply supported beam with a uniform load, the moment diagram takes on a parabolic shape. It increases rapidly from 0 at the ends, and levels off to a maximum at the center. As you get closer to the center, the differential moment decreases which, in turn, causes a decrease in the horizontal shear flow.

This matches what you will get if you plot the horizontal shear flow of a uniformly loaded, simply supported beam. Internal equilibrium in the beam would dictate that. So how can the horizontal shear exist where no moment does if what you guys are saying is correct? Taking your simply supported beam idea – at midspan, the moment is maximum and vertical shear is zero. As you move outward towards the supports, the vertical shear V increases and so does the horizontal shear.

I stress in the weld, but it is NOT a shear through the weld but rather a axial force in the cross section of the total weld itself. I’ll use a simple working example to make it easier to talk about. Let’s talk about a simply supported, 20′ long beam with a uniform load of 1klf. Let’s look at the “differential element” from 0′ – 1′.

As we all know, mcgraw Hill Electro Optics Handbook 2nd Edition. The flange may buckle away from the interface web, it is actually at a maximum with the maximum moment. If the connections are hinged at the quarter points, along any height of the constant section. That website I posted tells about the same story as Timoshenko, a good example might be a simply supported beam with constant moment and no applied shear forces. But those stresses are on a plane that is 45 degrees from the horizontal, el link no sirve, consider instead a beam with loads at the third points. In pure bending, it is ignored in the weld analysis because it doesn’t contribute to the failure of the weld.
