Nonlinear FE analysis of the ultimate behavior of steel castellated beams

Journal of Constructional Steel Research, 2012
Abstract A numerical model is developed to predict the behavior of castellated beams with hexagonal and octagonal openings up to failure. The numerical model takes into account both material and geometric nonlinearities. To initiate buckling, an initial small out-of-plane geometric imperfection, obtained from an eigenvalues buckling analysis, was ...

A new prediction model for the load capacity of castellated steel beams

Journal of Constructional Steel Research, 2011
Abstract In this study, a robust variant of genetic programming, namely gene expression programming (GEP), is utilized to build a prediction model for the load capacity of castellated steel beams. The proposed model relates the load capacity to the geometrical and mechanical properties of the castellated beams.

Comparative Study on Weight Efficiency of Castellated Steel Beams and Conventional I-Beams

International Journal of Research and Innovation in Applied Science
In modern steel construction, reducing self-weight while maintaining structural adequacy is a key design objective. Castellated steel beams, fabricated by introducing web openings into rolled I-sections, are widely recognized for their enhanced depth and improved structural efficiency.

Full Height Rectangular Opening Castellated Steel Beam with Diagonal Stiffener

Applied Mechanics and Materials, 2018
The full height rectangular opening castellated steel beam failed in Vierendeel mechanism. This makes the flexural capacity of castellated steel beam is lower than the original IWF section. This paper discusses analysis and test result of a full height rectangular opening castellated steel beam with diagonal stiffener.

Assessment of load carrying capacity of castellated steel beams by neural networks

Journal of Constructional Steel Research, 2011
Abstract In this paper, load carrying capacity of simply supported castellated steel beams, susceptible to web-post buckling, is studied. The accuracy of the nonlinear finite element (FE) method to evaluate the load carrying capacity and failure mode of the beams is discussed.

Numerical Analysis on Lateral Distortional Buckling of Octagonal Castellated Steel Beams

2018
A numerical model is suggested to predict the behavior of alveolar beams to multiple octagonal openings up to failure taking into account material and geometric nonlinearities in calculation. This research is interested in the effect of web distortions in a lateral distortional buckling mode of the I-beams on simply supported subjected to a load ...
