I would like to design banisters, so I have created a set of members for this. The cross-section is a hollow section. Can the stability analysis be carried out on the entire structure, or do I have to convert it into an equivalent member design with the specification of all supports in STEEL EC3?
In RF‑/STEEL EC3, I activated gamma_M1 for the calculation of cross-section resistance, as I want to cover the stability analyses with the second-order analysis and imperfections. However, the cross-section analysis for my design is performed with 1.0 in Germany. Why?
