STRUT AND TIE METHOD

[4321g]

Is it allowed to use strut and tie method to design structural steel beam?

 

[swearingen]

Strut and tie was specifically developed for deep concrete beams with large loads.

The concepts used to develop it apply to steel, but there are already methods to design deep, high shear steel beams.

I believe the " Strut and Tie Model" developed for concrete beams was based on the " Tension Field Theory" developed for steel beams some 100 years ago.

I think yes, theoretically. Way back in college, I remember first learning about web shear stiffeners that way.

I am ignorant about steel strut and tie, I was told its application was to the D region of reinforced concrete. What parallel in steel will match the confinement of ties?

 

[ThomasH]

The strut and tie method is developed for concrete. You have the "truts", the compressed concrete, and the "ties", the contrete in tension, that you reinforce.

But there is no reason why you shouldn't be able to use the same kind of reasoning for steel. I can't really se any point in doing it but thats a another story. Just beware of stability criteria.

Try plate girders....that is essentially a strut and tie system.

The reason why i want used it is because I have Pile cap made up of three piles arranged in triangle which are link by steel beam that support logitidunal beam of a flatform.
