ABSTRACT:

The aim of this paper is to present a practical advanced analysis method for steel frame design, based on asimplified second-order elastic analysis of the structure with an equivalent geometric imperfection. The second order effects are calculated using the orthogonality properties of the buckling modes. The geometric imperfection is obtained from the buckling mode by a suitable scaling procedure using a generalization of Dutheil´s method.

 

Keywords:Advanced analysis, Geometric nonlinearity, Steel design, Steel frames, Geometric imperfection.
