Hello!
Currently new to SOFiSTiK. I have created a bridge with a double T-beam cross section and supports springs in the vertical direction at different spans. A line load of 99 kN/m is also applied. However, when running the analysis, I get an error that says “Very big displacement in instabilitycheck-LC 1001… at node 1 ! → WINGRAF u+phi”. Any suggestions on how I can solve this issue?
