Most of the castellated beams are fabricated from a standard universal I-beam or H-column, by cutting the web on a half hexagonal line down the centre of the beam, then these two halves are moved directly across by a half unit of spacing and re-joined by welding. The castellated beam is one of the steel members which uses less material, but has equal performance as the I-beam of the same size.Unbraced length of the beams pl ays an important role in their flexural capacity. Differences between typical beam design process and castellated beam design procedure.The spreadsheet suite includes 5 different types of analysis for castellated beams made from UC, UB and from RSJ sections. The CivilWeb Castellated Beam Design Spreadsheet Suite is an easy to use collection of spreadsheets for the design of standard castellated beam sections to BS EN 1992.Using these charts helps to quickly identify the maximum span length for 5 different categories of castellated beam solutions.The charts assume a partial safety factor, γ M1, of 1.0 according to EN. Standard Table: American, British and European Shapes. Composite and composite beams in steel grades S355, S460 and HISTAR® 460. ECCBEAM is used to design the castellated and cellular beamS of various shapes for Dead, Live, Snow and Wind loads and combinations. ![]() A new generation of cellular beams The cellular ACB® and Angelina™ beams, with their circular and sinusoidal web openings, elegantly. To aid this process, the Cellbeam software package can be used to design an automated beam of fixed depth to match the restriction faced by the designer.
