Castellated Beam Web Buckling in Shear
Journal of Structural Engineering, 1998Tests of four castellated beams are described, in which the buckling of the web-post between openings was the focus of interest. Evidence of web-post buckling was observed in all test beams, although one also underwent lateral displacements. Elastic finite-element analysis was used to predict the buckling loads.

Bracing requirements for inelastic castellated beams
Journal of Constructional Steel Research, 2005Lateral–torsional buckling can be avoided by properly spaced and designed lateral bracing. Bracings are usually assumed to be elastic, and so may be characterized by their elastic stiffnesses. It is well known that an elastic lateral brace restricts partially the lateral buckling of slender beams and increases the elastic buckling moment.

Castellated Beam Deflections Using Substructuring
Journal of the Structural Division, 1977Several approximate methods are presently available for calculating deflections in castellated steel beams, yet, none is very accurate. Using Pippard.s approximate method of analysis of open-panel structures, Gardner was able to predict deflection to within 5% or better in several simply supported castellated beams; the method, however, involves ...

Shear response of castellated steel beams
International Journal of Steel Structures, 2015Because 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

Reliability Analysis of Litzka Castellated Beams
Ibero-Latin American Congress on Computational Methods in Engineering (CILAMCE)This paper presents a safety evaluation of Litzka castellated beams, based on calculation models proposed in the technical literature. It is noteworthy that there are currently no applicable Brazilian standards or official design criteria for this type of structure.

Numerical modelling of castellated beams with hexagonal openings
World Journal of Engineering, 2012In this paper, a numerical model is developed to predict the behaviour of castellated beams with hexagonal. The numerical model takes into account both material and geometric non-linearity. To initiate buckling, an initial small out-of-plane geometric imperfection, obtained from an eigenvalues buckling analysis, was imposed to the model.

WEB POST STRENGTH IN CASTELLATED STEEL BEAMS.
Proceedings of the Institution of Civil Engineers, 1985An 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
