Hi everyone,
Currently I am working with nonlinear static pushdown analysis in SAP 2000. I understand that when the analysis gives a warning 'unable to find a solution at step 20' means that the assigned hinges are compete to unload i.e where one hinges requires the applied load to increase while the other requires the load to decrease.
My question is, how are we going to overcome this warning?..Is there any better solution for this?
Looking forward for anyone to reply.
Best Regards,
Hazrina Mansor
