Numerical analysis of castellated beams with oval openings [PDF]

MATEC Web of Conferences, 2018
The use of castellated beams has become more popular in the last two decades. The main idea for the use of these types of steel beams is to reduce their self-weight by providing openings in the web of wide flange (WF) or I sections.

Study on the Fire Resistance of Castellated Composite Beams with Semi-Rigid Restraints

Buildings
To study the fire resistance of castellated composite beams with semi-rigid restraints, temperature rise tests with constant loads were performed on two full-scale castellated composite beams with circular holes and semi-rigid restraints to compare the ...

THE FLEXURAL BEHAVIOR OF COMPOSITE HYBRID CASTELLATED I-BEAM

Mağallaẗ Al-kūfaẗ Al-handasiyyaẗ
This study examines the flexural behavior of six hybrid composite castellated beams with varying castellated degrees (25%, 33.8%, and 50%). Hybrid beams are formed by utilizing plates with different strengths in the compression and tension zones.

Castellated beams

, 2023
Tema ovog završnog rada su saćasti nosači. Saćasti nosači su čelični nosači koji imaju šesterokutne otvore u hrptu. Izrađuju se iz punostijenih nosača uzdužnim rezanjem hrpta te zavarivanjem duž ruba otvora.

Reinforcing the Octagonal Web Openings of Castellated Beam by Steel Rings

Al-Qadisiyah Journal for Engineering Science, 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.

Investigation of rational depth of castellated steel I‐beams/Sijų su perforuotąja sienele racionalaus aukščio tyrimas

Journal of Civil Engineering and Management, 2008
There are many methods to calculate castellated steel beams; however, neither of these methods determines the rational cross‐section selection. Selecting the rational cross‐section induces a significant reduction in the quantity of steel. A new algorithm
