what information I shall pay attention when read last analysis Run Log (after non linear analysis)

[donnabean]

Hello all,

I am learinging ETABS now, have a couple questions would like to ask. Appreciate any input and thought.
1) what I shall pay attention to the analysis log after running linear static and non linear statice analysis. The model is one story, tension only brace steel structre building.

2) how to reverse or delete a non linear statice load combination.
I convert seismic combos to nonlinear cases, but later on I want y direction brace change to hss brace, which can take compression and tension. in my project, seismic control y direction. So how can i reverse my y direction seismic combo back to linear static load

Thanks in advance

look for warnings with solution lost values of 11 or more and edit your model accordingly. scroll down below to the percent of errors which should be more than e-11
