sol tol
<t>Hi, <br/> <br/> I am doing a model which tests a composite beam-column sub assemblage. The model requires the use of "hinges" connected sometimes up to 4 elements. I have modeled the "hinges" as link elements which have a very high stiffness in all DOF except the M2 DOF which is very small. When ...

Re: Stiffness in the M2 DOF
<t>Hi, thanks for your previous reply. I have tried what was suggested. For the most part it works. However, When I need to utilize a linear-asymmetric link, the F3 DOF needs to be about 60kN/m and the M2 about 50. I want to create a spring that is completely rigid when compressed, and 0 stiffness w...

Stiffness in the M2 DOF
<t>Hello, <br/> <br/> I am trying to model a steel panel zone by having rigid elements (1m x 1m) as a rectangular perimeter and then a diagonal element connecting the opposite corners of the perimeter. The diagonal member is broken into two parts and a spring with only axial stiffness is added where...

could not re-orthogonalise all Lanczos vectors
I am trying to model a sub-assemblage of a composite structure. When running an eigenvalue analysis I get this response:
Warning: could not re-orthogonalise all Lanczos vectors.
What does this mean? and how can I fix this?

panel zone frame model
<t>I am trying to model the panel zone(s) of a composite sub-assemblage. In the model I am using there is a panel zone where the steel beam connects to the steel column and a panel zone above it where the concrete slab connects to the steel column. If I use rigid elements to represent the parameter ...

Reinforcement in Composite Beam
<t>I’m trying to model a sub-assemblage of a steel column, steel-concrete composite beam. In the section tab the section type would be “cpis” however, I don’t see how the section allows for the influence of reinforcement in the slab. Is there a different way to model a composite beam which would acc...
