Code-check of steel members with buckling problems

[@c8y8r8]

Thank you for your very good and detailed demonstration, how do you relate Ec3 clause 5.2 Alpha Critical to Buckling factor? If BF >1 , no 2nd order analysis is required?

[@ideastatica_en]

Hello, you consider the 2nd order analysis based on the alpha critical that comes from the global structural model (should provide you e.g. SAP2000, Robot, etc.). This is something different from the buckling factor, which is calculated in IDEA Member for one or more members selected from the global structural model.

Hello, how to devide the element be 3 part and put end plate moment connection between in the 3 part of the element?

Hello, you can input more members for the analysis and connect the with a modeled connection, as for example here: www.ideastatica.com/support-center/steel-frame-en
