PRE-MIXED: High-Performance Buildings with a Combination of Vertical and Horizontal Structural Systems

PRE-MIXED is a building system in which the vertical load-bearing elements (columns and shear walls) are cast-in-place reinforced concrete, while the horizontal load-bearing elements (beams and slabs) are prestressed concrete.

PRE-MIXED System Experiments at ITU:
Experimental studies and theoretical calculations carried out at Istanbul Technical University (ITU) Earthquake Laboratory have demonstrated that the PRE-MIXED system performs excellently under reversible seismic loads. This system, which behaves similarly to cast-in-place systems, has been registered as a utility model.

PRE-MIXED offers a highly efficient and flexible building system. It stands out for both its performance and cost-effectiveness, providing tailored solutions for various construction needs. Ideal for high-rise buildings, PRE-MIXED is a significant technology in the industry with its durability and rapid construction capabilities.

Key Advantages:

  • Application in High-Rise Buildings: Thanks to the use of shear walls in the load-bearing system, it can be successfully applied in high-rise buildings.
  • Fast Construction Process: The tunnel form construction method allows for high-speed construction. (For example, in the Yakupoğlu project, 3,000 m² of floor construction was completed in just 10 days.)
  • Cost-Effective: It can be constructed at a cost competitive with cast-in-place reinforced concrete systems.
  • Flexibility: The PRE-KARMA system is more flexible than fully prefabricated systems when it comes to plan irregularities.
  • Ideal for Medium-Height Structures: Suitable for buildings ranging from 5 to 20 stories.
  • Solution for Long Columns: For buildings requiring columns longer than 30 meters, using precast columns eliminates problems related to transportation and placement.

Applications:

  • Low and High-Rise Buildings:
    • Logistics Warehouses
    • Industrial Buildings
    • Office Buildings
    • Residential Buildings
    • Shopping Centers
    • General Service Buildings
    • Educational Buildings
    • Shopping Malls (AVMs)
