hi everybody.
i'm doing NTHA for a rc moment frame with brb. by using different algorithms,integrators and dts ,analysis fails at 6 or 12 seconds and when i use below analysis options the analysis stops at 15.2913 second and does not progress(with no error and no warning)why?
algorithm newtonlinesearch
integrator HHT 0.5
dt 0.00025

Hi Saharnaz,

Have to check the period of the frame? Could you please tell what tolerance limit you used in the analysis? I think the modeling assumptions in the brb may influence the respone of the brb, which may change your response.
