How to find out of plane Displacement for the curved girder during erection
Question:
I am trying to determine the curved girder out of plane displacement during erection of a dual girder lift by the crane - can you give guidance on how i can model the girders up in the air held by a crane to determine this rotation?
Thank you

Hello,
Greetings.
Thanks for reaching us.
Provide the support conditions at the crane cable locations. The support conditions are provided with help of point spring supports with stiffness as shown below.
Node 36 is one end girder and node 66 is other end and are the locations from where girder is lifted.
