Revision of EN 1993‐1‐1 – Design rules for structural analysis, cross‐sectional resistance and member buckling

چکیده
In the framework of revision Eurocode 3, Part 1–1, several amendments have been proposed and accepted in order to improve rules for resistance member buckling. For clarification, a flow chart connecting global analysis (first or second order), imperfections type verification has implemented ease use. Since publication standard 2005, many research projects conducted across Europe on this topic their results contributed provide appropriate answers problems identified practice. Therefore, revised code provides new design stability. Important works calibration performed these different derive values partial factor side. example, formulation lateral–torsional buckling introduced calculation reduction factor. The consequence is discrepancy between obtained by methods those from experimental numerical tests. extend scope additional an annex cover stability members with mono-symmetric cross-section under compression axial force, biaxial bending, without torsion. format criteria remains similar current interaction formulae so that designers can easily identify evolution rules. This article presents systematic way implementations formal vote version FprEN 1993-1-1 code.

In this study, buckling analysis of panel types of marine and offshore structural components with initial imperfection under the combined action of lateral pressure and axial compression is carried out. The governing differential equations for thin and moderately thick shells are developed in terms of components of the displacement field. The governing ordinary differential equations are then d...

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
