Precast concrete beams are often used in buildings to carry floor slabs. A special type of beam concerns a precast beam where stirrups are protruding on the topside such that in a later construction stage a cast-in-situ top layer can be added. This can give several advantages, but how to model it? Prefab betonbalken worden in gebouwen vaak gebruikt om vloerplaten te dragen. Een speciaal type balk betreft een prefab balk waarbij aan de bovenzijde beugels uitsteken zodat in een latere bouwfase een in het werk gestorte toplaag kan worden toegevoegd. Dit kan verschillende voordelen bieden, maar hoe moet dit worden gemodelleerd?

In this webinar you can learn how to model, design, and check RC composite beams taking into account staged construction.

Making the beam behave as a continuous composite beam

After the top layer of concrete has hardened the structure will act as a composite beam, this gives the advantage of increasing the stiffness and capacity of the beam.

Moreover, beams that initially behaved as separate simply supported beams can now be coupled together such that they will act as a continuous beam over multiple supports. The additional load coming from the floor slabs and variable load will then be carried in a more efficient way with lower field moments and the possibility to transfer negative moments at the supports.
