When numerical models are used to predict behaviour of open thin-walled steel cross-sections, the nonlinear analysis results can be influenced by the magnitudes introduced as initial imperfection. At present, a wide range ...

Aquest informe té per objectiu comparar els resultats d'anàlisi geomètricament no lineals tipus co-rotacional i tipus matriu de rigidesa geométrica fets en estructures de prestatgeries. També s'avalua la sensibilitat de ...

In the race for developing aircraft with lighter airframe, aiming at increasing aircraft payload and/or fuel efficiency, the shift from conventional metal structures to light-weight composite structures has attracted ...

The investigation attempts to adapt a be am finite element procedure based on the Generalised Beam Theory (GBT) to the analysis of perforated columns. The presence of perforations is taken into account through the use of ...

This paper presents numerical simulations of a suite of cantilever seismic tests of speed-lock connections between beam and upright members of adjustable pallet rack systems. The tested specimens differ in the endplate-to-beam ...

Starting from a comprehensive set of experimental test results of upright cross-sections in compression, this paper is focussed on how the section can be optimally designed to achieve the highest possible failure load ...

When non-linear finite element analysis (FEA) of cold-formed thin-walled steel sections subject to compression is carried out, an initial perturbation must be introduced in the model in order to trigger the failure due ...

El presente libro es una colección de problemas resueltos, destinada a facilitar el aprendizaje de la resistencia de materiales a través de su aplicación a ejemplos concretos. Ha sido elaborado pensando en su uso por parte ...

This paper presents three methodologies to predict the load carrying capacity of cold formed steel rack columns via nonlinear finite element analysis (FEA). The column lengths are chosen in the range where the main failure ...
