The development consists of three luxury 40 storey apartment towers with three car park basements.
The project is located in South Jakarta and consists of 3 towers of 40 storey each combined with a 3 basement podium with approx. 86.000m2 total floor area.
Each tower is structurally unique to the others and connected at the podium. TTW provided structural system and Etabs building modelling to achieve the required timeframe. Our engineers designed the diaphragm and collectors at GF by combining the three towers with the three basement podiums in order to achieve the maximum forces acting on the diaphragm.
The slabs of the towers were modelled as shell-thin and semi-rigid diaphragm with 5% flexural stiffness modifier (this induces additional torsional force at the perimeter beams).
