X bracing
X bracing
(OP)
In X bracing (tension only brace) frames, what is the basis assumption of tension only brace. I think when we provide bolted connections (no slots), there is always compression in the brace subjected to shear? The brace in question carries 80 kips compression resulting in big member, & in tension only case, results in small section.
Any force transfer mechanism (for tension only case)??
Thanks

RE: X bracing
When this happens, the relative stiffness of the tension brace (AE/PL) is much higher than the semi-buckled compression brace and thus all or most of the load goes into the tension brace (Hooke's Law).
This can especially be visualized if you consider small steel rods as the brace members - a high strength steel tension rod vs. a wet noodle compression rod.

should i now reconsider this approach..
what happens if the WT can actually take the compression..
should i still consider v brace as tension member only..

I agree with the point made by agostage, design the members according to the theory you choose, tension only or reversible tension-compression or truss; just be consistant.
