Cellular beam

Cellular beam is a further development of the traditional

building construction.[2]

The difference between cellular beam and castellated beam is the visual characteristic.[3] A cellular beam has round openings (circular pattern) while the castellated beam has hexagonal openings (hexagonal pattern), both of which are achieved by a cutting and welding process.[4] Cellular beams are usually made of structural steel, but can also be made of other materials.[5] The cellular beam is a structural element that mainly withstands structural load laterally applied to the axis of the beam, and influences the overall performance of steel framed buildings.[6] The type of deflection is mainly done by bending.

Introduction

In 1987, Westok Structural Services Ltd of Wakefield invented and patented the structural steel cellular beam.[7]

In 2009, the Steel Construction Institute developed software to assist engineers evaluating the dynamic behaviour of composite floors supported by cellular beams.[8]

Since 1940, civil engineers have endeavoured to find solutions to reduce the cost and weight of steel frame construction.[9] Due to the restrictions with regard to the maximum permissible deflections, the high-strength properties of structural steel cannot always be optimally used.[10] As a result, several new steel mixtures have been identified to increase the stiffness of steel components without significantly increasing the required steel weight.[11] The use of steel girders with web openings (SBWOs) for structures such as industrial buildings has proven to be extensive.[12] Civil engineers came up with a solution to use a composite design of ultra-shallow floor joists together with concrete used on the Douala Grand Mall in Cameroon.[13] Since the 2010s, further investigations into steel construction and fire protection have been carried out,[14][15] which led to innovations in the field of passive fire protection that could save lives and assets.[16]
