Lateral Instability of Castellated Beams
Engineering Journal, 1974The study reported herein deals with the lateral instability analysis of castellated beams using the principle of minimum potential energy. Several experiments available from the literature provide information for selecting the deformed configuration which satisfies the conditions of both statics and geometry at the boundary; certain idealizations are ...

Parameteric Study of Castellated Beam
Advanced Materials Research, 2010“Castellated beam” is a name commonly used for type of expanded beam. Castellated beams combine beauty, versatility, economy in steel design. These are fabricated from standard rolled section and are engineered to save time of construction, enabling saving in steel and reducing building costs.

Numerical Modeling of Composite Castellated Beams
Composite Construction in Steel and Concrete VI, 2011In modern composite structures, higher steel grades are used for structural steel profiles in order to increase span capacity without an unnecessary increase in the composite floor depth. This tendency results in beams that are more vulnerable to the failure modes that involve either web LSB (local shear buckling) and/or compression flange RDB ...

Finite element analysis of castellated beams
Computers & Structures, 1978Abstract A method of analysis for the deflection and stresses in castellated beams or also beams with web openings has been presented in this paper using finite element method. A generalised programme for the use of IBM 1620 is also developed. An experimental programme to evaluate the theoretical solution was conducted using five number full sized ...

Experiments on elastically braced castellated beams
Journal of Constructional Steel Research, 2012Castellated beams are widely used as flexural members in steel construction. The economical and structural advantages of these elements have prompted many researchers to investigate the failure behavior of such structures. Despite numerous reported researches on the buckling stability of castellated beams, no experimental study is found on lateral ...

Behavior of composite castellated beams
1997While the study of non-composite castellated beams have received much attention, very little work has been done on composite castellated beams. The effect of the composite concrete slab is to significantly increase the flexural resistance of a steel section; it is however uncertain what effect this will have on the shear resistance.

Castellated Beams - New Developments
Engineering Journal, 1964"Castellated beam" is a name commonly used for a type of expanded beam. It is made by expanding a standard rolled shape in a manner which creates a regular pattern of holes in the web. The name is derived from this pattern of web holes, because castellated means "built like a castle, having battlements, or regular holes in the walls, like a castle ...

Behaviour of composite castellated beams
Progress in Structural Engineering and Materials, 2000The effect of composite action on the behaviour of composite castellated beams is described by comparison with that of non-composite beams. It is demonstrated that enhancement of both flexural and shearing resistances can be expected, but that the improved shearing resistance can only be realised if certain conditions are met. The role of partial shear

Rotational capacity of castellated steel beams
The Structural Design of Tall and Special Buildings, 2012SUMMARYThis 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 ...
