Abstract

The focus of this work is the parametric analysis of the stability of G and spatial frames with an introduced initial geometric imperfection. It investigates the influence of different types of angle stiffeners (box, diagonal, and combined) and numerical factors (mesh element type and mesh size in Abaqus) on the stability of these structures, with the aim of optimizing their design.
