https://forums.autodesk.com/t5/robot-structural-analysis-forum/elastic-release/m-p/5887854#M59826 I'm modelling simple frame symmetry (Rc Column with steel rafter) in Autodesk Robot Structural analysis 2012with two cases. - column fix 100% with rafter (00000A1) - column fix 20% with rafter (0000A2) The result is, first case, moment is symmetry, but other case is not symmetry. Why? What's wrong? No wind load!! Model is symmetry!!! Mon, 02 Nov 2015 02:02:44 GMT e2009355 2015-11-02T02:02:44Z
