Structural behaviour of castellated steel beams with reinforced web openings

Asian Journal of Civil Engineering, 2020
In recent years, castellated steel beams, in steel structure buildings, have been employed extensively. There is common practice of adopting the depth of web openings up to 80% depth of the section. Due to large depth of web openings there is drastic reduction in the stiffness of the beams.

Rotational capacity of castellated steel beams

The Structural Design of Tall and Special Buildings, 2012
SUMMARYThis paper numerically studies the behavior of castellated beams with two simply supported ends under moment gradient loading and investigates the effect of beam and braced lengths on rotational capacity of castellated beams. To assure the ability of numerical models in predicting the complex behavior (especially at the location of opening) as ...

Shear response of castellated steel beams

International Journal of Steel Structures, 2015
Because of non-ductile nature of buckling mode of failure, web-post failure examination of castellated steel beams is considered a critical issue in designing. A detailed numerical study is performed on the shear response of castellated steel beams, susceptible to web-post buckling in this article. The accuracy of the previously proposed formulation is

Experimental study for improving behavior of castellated steel beam using steel rings

Pollack Periodica, 2021
AbstractCastellated beams are made from a hot rolled steel I-section in a few steps. Firstly, the web of the parent I-section is cut in a particular zigzag pattern and the two halves are reconnected by welding to form a castellated beam with hexagonal openings.

WEB POST STRENGTH IN CASTELLATED STEEL BEAMS.

Proceedings of the Institution of Civil Engineers, 1985
An experimental study is reported in which 16 castellated beam specimens of the standard British module have been subjected to locally applied compressive loading over a web post. Experimental failure loads were found to be relatively insensitive both to cross-section geometry and to the exact way in which the load was introduced into the web post. The

OPTIMUM EXPANSION RATIO OF CASTELLATED STEEL BEAMS

Engineering Optimization, 1975
Abstract In this paper, the authors present a numerical analysis for the optimum expansion ratio based on the elastic as well as the plastic method of analysis. The elastic analysis program is based on an iterative process and involves the calculation of allowable loads corresponding to potentially critical flexural and shear stresses at each increment

Behaviour of composite frames with castellated steel beams at elevated temperatures

Advances in Structural Engineering, 2016
The behaviour of composite frames with castellated steel beams at elevated temperatures is investigated, and the results obtained were compared with the companion results of simply supported composite castellated steel beams. Overall, it is aimed to investigate the effect of axial and rotational restraining of the steel beam via rigid connections with ...

Behaviour of normal and high-strength castellated steel beams

Proceedings of the Institution of Civil Engineers - Structures and Buildings, 2012
This paper investigates the design and behaviour of normal- and high-strength castellated steel beams under distortional buckling. An efficient non-linear three-dimensional finite-element model has been developed for the analysis of the beams. The initial geometric imperfection, residual stresses and material non-linearities of flange and web portions
