Hi, I'd like to simulate the NL bahavior of a 15m column and I am not sure what kind of elements I should use (force-based or displacement-based). If I use force-based elements, then I should use one and only element with the max number of integration points for the column or can I use more than one...

Thank you Vesna for your reply!

Hello, I am using nonlinearBeamColumn element and I want to assign element mass density (per unit length) in order the lumped-mass matrix to be formed. element nonlinearBeamColumn $eleTag $iNode $jNode $numIntgrPts $secTag $transfTag <-mass $massDens> <-iter $maxIters $tol> <-integration $intType> T...

Thank you very much Vesna for your reply but I am still a little confused.. The fact that there are only 3 displacements and 3 rotations for the zerolenght element and not 12 (6 at each node) does it mean that it responses like a rigid body? In the case of an elasticPPGap element if all nodes are co...

Thank you Vesna. If I use the code lines that change the algorithm whenever is necessary than the analysis may be complete. The problem is that I don't take reasonable results.. Could you please tell me if the connections among the zerolength elements and the elastomeribearing are correct? I mean is...

Thank you very much for your reply. I get the following message: WARNING: CTestEnergyIncr::test<> - failed to converge after 1000 iterations ModifiedNewton::solveCurrentStep<> - the ConvergenceTest object failed in test <> DirectIntegrationAnalysis::analyze<> - the Algorithm failed at time 4.449 Ope...

Dear Vesna, I'm trying to simulate the boundary conditions at the deck ends of a bridge and I want to consider the embankment flexibility. I used an elastomericBearing element for the bearing and a zerolength element with the Elastic-Perfectly Plastic Gap Material for the gap between the deck and th...

Thank you very much for your reply. I used =xml and I took the following but I am still confused.. I mean that the deformations are referred to the whole element while the forces are at each node end? And the order is F1,F2,F3,M1,M2,M3 at start node and F1,F2,F3,M1,M2,M3 at the end node? Thanks agai...

Hello, I have a question regarding the recorders of zerolength elements. For example, I assigned the ElasticPPGap material in a zerolength element and I want the forces and displacements so I used 'force' and 'deformation' recorders. When I open the .out files, the file with the displacements contai...
