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.
With the add-on modules RF‑TENDON and RF‑TENDON Design, you can design structural components with pretension.
