Column-slab joint for multi-storey construction with high strength materials

In high-rise construction, problems may occur due to the normal force transfer from column to column through a column-slab joint. For this reason, TU Wien has developed a particularly favourable embodiment for a column-slab joint, in which an in situ concrete slab with regular concrete strength is located between two high-strength precast columns. In the precast columns, the cross-sectional dimensions of the column ends are increased to transfer the normal force through the slab without a reduction of the load bearing capacity when compared to the column. Prefabricated columns of high-strength concrete can be created more slender and the thickness of the reinforced slabs can be further reduced in comparison to the state of the art.

• Slender precast columns using high-strength materials for multistorey buildings
• Increase in usable/rentable floor space
• Reduction of the thickness of the slab
• Savings in material and weight
• Lower transport and crane costs

Prototypes are available at TU Wien.

TU Wien is looking for companies in the field of Architecture and Civil Engineering that are interested in license agreements and project based cooperation.
