Reinforcing the Octagonal Web Openings of Castellated Beam by Steel Rings

open access: yesAl-Qadisiyah Journal for Engineering Sciences, 2019
Castellated steel beams are section steel members with hexagonal or octagonal web openings which they are made from standard hot rolled steel section I or H. The main advantage of these members is their economic material. An additional important advantage is a possibility to guide service ducts through the openings.
