IDA ANALYSIS OF FRAME STRUCTURE

[SUJOY]

I've tried to do the IDA analysis for frame structure but IDA curve is not somehow satisfactory and even the openseas is crashing during running at higher scales. How can I sort out the issue?

"Satisfactory" is subjective when it comes to IDAs. Why would you expect a nonlinear analysis to converge at all higher scales? You will need to assess the constitutive models, algorithm, convergence tolerance, time step, etc.
