I'm having issues with the different methods of analysis', I can get results for Perform Analysis but when I try to switch to P-Delta and Direct Analysis I get warnings about instabilities and error codes in the output such as 1.#INF, 1.#IND and 1.#QNAN. There are both moment connections, pinned connections and pinned connections with springs to overcome tempurature forces. All load combinations that this effects has to do with the following load cases:
7. TL (temperature load)
10 WL1(+Z)
11. WL1(-Z)
14. WL2(+Z)
15. WL2(-Z)
16. WIL2(+Z)
These load cases appear to be what is giving me trouble. Any help would be great.
