Transfer load from bottom flange to top flange

[sun4163]

Hi
Could you please refer to the attached picture and show me the calculation of how to transfer the horizontal load of 5kN from bottom flange to top flange?

Thanks in advance

Brace it against the rotational moment, and apply the 5kN counterforce?

Not sure what else to say. You haven't given much to go on.

Hu Bridgesmith
Thanks for the reply.
Assume that there is no option to brace against rotational moment.could you please show me the calculation to understand that a hor. Load of 5kNon the bottom flange will have have what effect on the top flange and show some calculations to support it.

Thank you

The diagram you show it not in static equilibrium. If you don't know what that means then I suggest you go back to your first year engineering subjects. Also in the future please use the student forum if you are a student.

If it's not braced some against rotational moment, then it's not stable. It will rotate and continue to rotate until the force is no longer applied. It has to be restrained somewhere.

As human909 wrote, if you are an engineering student please post in the student section.

Don't mind the people bashing you. Structural Engineers is the most unhappiest profession in the world and most of them are real J***. They are very old school and have a kind of ego that's why they never end up rich like IT or other profession. They don't want people to progress since this will hurt their ego and they know nothing outside of structural engineering or don't have a life outside of it. Don't be like them. Break this norm.

So, in order to prevent that we provide stiffeners.

Whoa! What? That is not what stiffeners do. They do nothing to resist torsion or increase the lateral torsional buckling resistance of an open section.

Hmm...you should probably look for a broader brush. I don't think this one is quite sufficient...

sun4163 - what are you trying to accomplish? I know you want to 'get the load into the top flange', but why? What else is going on with this section? Is this a beam with deck fastened to the top and a wall fastened to the bottom? Part of a grillage assembly? A monorail beam with a lateral reaction from the trolley?

how to transfer the horizontal load of 5kN from bottom flange to top flange?

For a wide flange - you don't really. I'd typically use blocking, angle bracing, or bridging and bracing, and ultimately a diaphragm or perpendicular resisting element to anchor and resolve that load into. Depends on the context here, can you provide some more information?
