The behavior and design of longitudinally stiffened thin-walled compression elements

摘要

The behavior and design of cold-formed steel sections with single and multiple intermediate stiffeners in the compression flange is investigated. Existing experimental data are used to evaluate critically the AISI specifi- Cation and Eurocode. For bending strength prediction of sections with Multiple intermediate stiffeners, the AISI specification can be quite uncon- Servative and Eurocode often yields overly conservative results. Existing Experimental data are used to calibrate a finite element model. An exten- Sive parametric study is conducted using the finite element model.
