[1] The advantage of the steel beam castellation process is that it increases strength without adding weight, making both versions an inexpensive solution to achieve maximum structural load capacity in building construction.
[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.
[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.
