DLUBAL Composite Beam v8 (Full)

By Alexander Meierhofer, Dlubal Engineering Software

Precast prestressed hollow core slabs consist of composite, uniaxially stressed non-solid slabs with a width of about 1.20 m. These elements are prestressed with pre-tension in a precast concrete plant. The precasting is usually done with slipformers. Due to the lesser self-weight of the non-solid slab and the existing prestress, these precast prestressed hollow core slabs show a lesser deflection than loosly reinforced slabs made of solid concrete.
