Analysisi 0% in IDEA STATICA? Difficult to reach equlibrium load in this connection

[anggadiawan]

I'm having difficulities in analyze this type of connection, but if i remove all the beam except M1 and M2 I can analyze this connection. But I can't analyze if i include M3, M4, M5, and M6 or one of the that member. I used M1 as a bearing member and also having difficulitie to reac equilibrium in load. Does anyone know how to solve this??

Anggadiwan,

Looks like you are analyzing ridge connection with purlins. I will suggest to analyze ridge connection M1 and M2 only as one connection. And do the analysis of Purlin and rafter member as different connection (one purlin connection with Rafter with worst reaction is fine). There are soo many reason in Ideastatica to have 0% analysis.
Might be members not connection properly (see the purlin flange is not having proper contact with rafter member, in this case connection can be unstable hence not carrying any load). If Purlin connection is end connection then try it with N, Vx and Vy member. Also try to assign contact operation between purlin bottom flange and rafter top flange.

Easiest way to resolve like this error are
-Check the deflected shape, you will understand real behavior and the issue.
- check the warning or message by ideastatica.

Also I am surprise, why you are having two purlins each side.
