A vibration control structure to withstand earthquakes
The 28-story, over 100-meter full-service luxury rental apartments building Sakae Tower Hills has a vibration control structure.
Sakae Tower is built on 73 foundation piles that were driven to a depth of approximately 37 meters into solid ground.
The building was designed to provide a safe and comfortable place to live for its tenants.
Vibration control structure
In the event of any foreseeable large earthquake, for example the Nankai Trough earthquake, seismic control dampers will absorb the seismic energy of the quake, preventing damage to the pillar-beam frame of the building and keeping the structure from shaking excessively or warping.
-
Strong concrete
The building uses highly resistant concrete with a compressive strength of 30-70N/mm2. The concrete can withstand 3,000 to 7,000 tons of compression per square meter. (Excepting certain parts)
-
Water-cement ratio 0.50 or less
The water-cement ration is 0.50 or less to prevent cracking and the like. The concrete exceeds durability design strength standards. (Excepting certain parts)
-
Seamlessly welded hoops
The pillars that support the structure of the building are made more earthquake-resistant by wrapping them in hoops that are welded closed using seamless welding.
-
Axial reinforcement
Axial reinforcement (590N/mm2) increases the strength and toughness of the lower-level peripheral columns.
Axial reinforcement: The addition of reinforcing bars to concrete pillars to improve their resistance to the tensile force that acts on them during earthquakes, as concrete cannot withstand tensile force easily
Fireproofing and sound insulation
-
Outer walls
The ALC (aerated lightweight concrete) used for the outer walls acts as fireproofing, preventing the spread of flames.
-
Walls between units
The walls between units have a sound insulation performance of TLD-56.
This prevents sound from traveling between units.
- *TLD expresses the sound insulation performance (acoustic transmission loss) of a sound-insulating wall as measured in an acoustic test room.
- *A sound insulation performance of TLD-56 means that normal sounds such as from televisions, radios or conversations are virtually inaudible.
Comfortable spaces
-
Units
Concrete floors inside residential units are 250 mm thick, ensuring improved vibration and sound insulation.
Ceilings have no girders, making for wide and clean spaces.
-
Corridors
The corridors inside the building are designed to resemble a hotel's. Carpeted floors give the corridors an extra touch of luxury. Air conditioning inside corridors is monitored 24 hours per day to ensure your comfort until the moment you exit the building.
