Re: Bridge Model with Truss and Beam-Column Elements OR End Moments Release
Also check supports with only truss elements connected. I did fix the rotations of the supports with only truss elements the problem persists I checked the list of nodes (with only truss elements) with SAP I am out of ideas to check if I fixed the moments of the truss only elements... any suggestio...

Re: Bridge Model with Truss and Beam-Column Elements OR End Moments Release
Yeah I tried fixing the rotational DOFs of the nodes that connects only Truss elements (Fix NUMBER 0 0 0 1 1 1)
the problem persists
if there is any other alternative or something I might be missing I would appreciate the assistance
thanks!

Re: Bridge Model with Truss and Beam-Column Elements OR End Moments Release
Oh I assume I should just actually use the Fix command? I will try that.

Bridge Model with Truss and Beam-Column Elements OR End Moments Release
Good afternoon, First, I created a Linear Elastic model of a bridge on OpenSees, using all elements as Beam-Column elements. It worked, OpenSees perform the analysis and the results (Internal forces, reactions, displacements) match the results obtained using SAP2000. However, I am trying to run an a...

Re: Automatic geomTransf vecxz
You can do what's described in this post: http://portwooddigital.com/2020/08/08/a-vector-in-the-x-z-plane/ Python is shown in the post, but you can do the same thing with Tcl. Thanks, Scott. This helps a lot I used that algorithm and I have one quick question if the element direction coincides with...

Automatic geomTransf vecxz
Hello! I am wondering if anyone knows any tool to calculate the vecxz for the geomTransf command. I am modelling a large 3D bridge with frame elements (not truss) and I need to automate the calculation of vecxz for all the elements with different inclinations/angles. I just need the local z to be in...
