Hi,
How can I change the radius of curvature of a reinforced concrete straight beam inorder to come up with a curved beam?

Hi

I'm afraid you cannot, from the geometry as a straight beam means R = INF and INF is not really dealt with as a Parameter value. But if you make a laaarge radius its lmost a straight beam, no ?

But what is possible is to take a straight beam and apply a moment on one end and curve it at will ;)

Good luck

Hello Ivar,

Is it possible to bend a beam by applying a moment at both ends and, after that constrain the curvature of the beam to that shape for the remaining of the transient simulation (sort of a boundary condition)?

Thanks,
