Numerical simulation of composite steel-concrete alveolar beams: web-post buckling, Vierendeel and flexural mechanisms [PDF]
Latin American Journal of Solids and Structures, 2020 Abstract Composite alveolar beams consist in the union of two structural systems largely employed in civil construction sector: the steel-concrete composite beams and the alveolar steel beams. Thus, its use allows their advantages to be enhanced, enabling to design even larger spans and to achieve more economical and sustainable solutions.

Experimental study of the behaviour and failure modes of tapered castellated steel beams
Open Engineering, 2022 This article discusses the experimental testing of tapered castellated beams (TCBs) under mid-span concentrated load. These beams are created by cutting the webs of standard I-sections in a particular zigzag pattern and rejoining the two parts by placing

Assessing the Load-Carrying Capacity of Composite Castellated Beams by Finite Element Method [PDF]
Journal of Rehabilitation in Civil EngineeringThe utilization of composite castellated beams in structures is common due to the increased bending strength and stiffness of the beam. However, the presence of openings in castellated beams reduces their shear strength.

A review of progressive collapse research and regulations [PDF]
, 2014 History has demonstrated that buildings designed to conventional design codes can lack the robustness necessary to withstand localised damage, partial or even complete collapse. This variable performance has led governmental organisations to seek ways of
