The buckling mechanism of diagonally stiffened plates under the combined action shear, bending, and compression is a complex phenomenon that difficult to describe with simple clear explicit expressions. Predicting elastic coefficient accurately crucial for calculating load these plates. Several factors influence plates, including plate’s aspect ratio, stiffener’s flexural torsional rigidity, in...

To reveal the stable bearing capacity of a new semi-rigid dome structure, tensile–beam cable (TBCD), detailed numerical simulation and analysis 60 m model TBCD is conducted. Then, effects factors such as prestress level, original imperfection size, distribution, addition hoop tension rods on stability are investigated. The results show that unstable loads arranged from small to large in followi...

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 t...

Abstract This paper presents a three-dimensional beam element for stability analysis of elastic thin-walled open-section beams in multibody systems. The model is based on the generalized strain formulation. In this formulation, set independent deformation modes defined which are related to dual stress resultants co-rotational frame. characterized by strains or deformations, expressed as analyti...

the cadaver spine motion segment behavior under torsional load was evaluated with the disc intact, with partial anterior discectomy and with spacer insertion. the results of this study explain how anterior lumbar discectomy and interbody fusion (alif) affects the torsional stability of the motion segment. the pseudarthrosis rate of the anterior lumbar discectomy and interbody fusion (alif) is k...
