The Puri Indah Financial Tower is a 23-storey office building sitting on top of a 4-storey podium block and 4-level basement. The building has a total area of 66,688 square metres, with the typical floor area averaging 2,000 square metres.
The structural system consists of a dual reinforced concrete core wall and ductile open frame. Since the location of the core is offset to one side of the building, the building is very sensitive to torsional effects during seismic and wind events. To address this issue, a rigid tube core wall with high torsional stiffness was introduced. Using the proposed solution, 3D analysis showed significant improvement in the behaviour of the structure.
