Staad Pro's curve member function
Staad Pro's curve member function
(OP)
I need to model a curved truss.
I tried by using a single simple beam, a simple 2D frame. But I failed to get reasonable results. It is a 2D frame, but it gives me 3D results, and some totally unreasonable results.
I wonder it is something wrong with my model or the curve member function is just not stable yet. I am using Staad Pro v8i.
I appreciate any response!

BridgeEI, I thank you are right. It is tricky for curved members. When you say Staad is tricky, it is in general or just for curved member? I am curious.
ToadJones,
My current model is using straight lines to approximate the curved sections. Over 45" span, the center offset from the curve is 1". Is that close enough? I was asked to add more nodes to make them closer to the curved. I want to add one more node, instead of 3 more nodes which I was asked to do.
Thanks!

Thanks very much. I used pinned supports, maybe that is the reason it resulted in unreasonable results.
I think I have to give up the try. I need to model curved members using small straight segements.
Thanks very much!
