How to simulate a rigid beam?
How to simulate a rigid beam?
(OP)
I want to run a nonlinear static analysis of a 7 floor building with frames and walls.
I found in this site that, in order to simulate the plastic hinge at the bottom of the wall, i have to assign the wall as a frame section. So the beam which is framing into the wall, has to be broken into two different elements:
1)The normal section of beam, which is deployed until the point where the wall theoretically begins, and
2) A "dummy" rigid beam (inside the wall) which connects the "wall" frame section (centerline of wall), to the end point of the normal beam.
How can i simulate this rigid beam? I tried to use a material with no weight and a modulus of elasticity with a very high price, E=1.0e+11, But i observerd that these dummy beams create some giagantic forces and moments at the wall!

I am making the model from zero, again, and i will place the wall between two dummy beams (in a row), at every floor. (The transverse beam to the wall will be a normal one)
I was wondering if the command:
Assign > Frame > End Length Offsets, would work instead of these rigid "dummy" beams?

I will try joint constraints too.
