The option is used to determine appropriate, code-specific parameters of lateral buckling depending on a member static scheme. It is accessible after pressing the appropriate icon located in the Lateral buckling parameters field in the Member Definition - Parameters dialog box.
The option is used to determine appropriate, code-specific parameters of lateral buckling depending on a member static scheme. According to the code requirements provided in appendix 1 to the code, the simply supported beam scheme or the cantilever scheme should be adopted. Selection of the last icon means that lateral buckling effects will not be considered in calculations.
