Hi, I am modelling a steel structure and doing time history analysis with shear walls having fibre hinges. I am getting the following error "General wall hinges are not modelled in links and will be linear for FNA load cases". In CSI site, it is stating that " hinges are not active during...

Hi, I am running a linear modal analysis for my 6 storey steel structure, I am getting the error as "Numerical problems encountered during equation solution" with the following table * * * W A R N I N G * * * NUMERICAL PROBLEMS ENCOUNTERED DURING EQUATION SOLUTION: TYPE LABEL DOF...

Thank you, I have already ran the static analysis with standard solver in etabs to check for instability but it doesnt have any. I will start with floor by floor as you suggested

Hi, I am doing a Non linear push over analysis in etabs for 6 storey steel building. Every time, I run the analysis, I am getting different curves even though there is no change in the model and I am not able to understand which one is correct. I am using the following solver settings and non...
