Monrail Modelling
Monrail Modelling
(OP)
Hi all,
Newly grad and newbie to Risa :)
I need to check the capacity of junior beams supporting a monorail at their midspans.
Modelling the junior beams are simple enough (about 6 beams spaced at 5.5ft), but I'm stuck at trying to model the monorail (S10x50) supported by the junior beams at their midspans. The monorail beam should be "hanging" , but modelling it just makes the beam cut "through" the supporting beams like a horizontal bracing. Is this the correct way of modelling it?
Any help would be appreciated

RE: Monrail Modelling
If, however, you are primarily concerned with lateal loads in the monorail (and how this can cause moment in the supporting members) then you could model the vertical offset between the two members. There is a section in the Modeling Tips section of the RISA-3D help file which talks about using rigid links to model one beam crossing over another. I believet that is similar to your situation.
RE: Monrail Modelling
You can also apply loads to the S10x50 either by using the "moving load" module of RISA or by suing rigid links to simulate the vertical offset.
A secondary check would be to look at the flange loading per the Crane Manufacturers Association of America spec #74.
