TRADEWINDS SQUARE TOWER
INVITED COMPETITION
Kuala Lampur, Malaysia
Structural System Concept:
The main tower structure is envisioned primarily as a concrete structure for core and columns with composite floor decks and steel outriggers. The lateral resisting force system shall utilize the core walls and columns through the perimeter moment frame and outrigger.
The system provides an efficient structural system that utilizes local construction expertise, and accommodates local structural requirements and
the opportunity for fast erection and construction. Further, the system offers the opportunity to integrate the skin and exo-skelton architectural systems to the primary structural systems.A primary concrete core runs throughout the tower, decreasing in size towards the top of the tower. Four Belt Truss - Outrigger Floors occur throughout the tower to link perimeter columns to the core. Each outrigger level shall be two floors deep. Floor slabs are designed as composite deck for rapid and efficient construction. Vertical and inclined concrete columns are located at the perimeter ofthe towel floor plans. The foundation system for the core and columns shall utilize a continuous thick pile cap below parking levels. Piles shall be used as the deep foundationsystem for both the core and columns. A finite element model was developed based on the proposed design, and analysis was undertaken to validate the viability of lhe design and tis structural requirements.
Performance & Optimization:
The unique design of the tower unviels an opportunity to Investigate innovative, efficient and cost-effective solutions through our expertise in developing high-level modeling, analysis and simulation; combined with external geotechnical
and wind tunnel sludies. and also internal expertise in building enclosures, facade design and engineering for an integrated design solution.
Facades and Sustainability Systems:
The organic nature of the design offers the potential of investigating innovative solutions for the facade systems integrating the structure in a sustainable manner.
On a structural standpoint, the organic form can be optimized with biomimetic strategies to mitigate wind loads and allow for an aerodynamic and efficient structure with reduced wind loads. The building skin and exo-skeleton can be designed for passive optimization of shading and daylighting, decreasing energy loads and mechanical requirements for the tower. Additionally is an opportunity to couple the system with a active components for ventilation to increase efficiency, enhance thermal comfort and reduce operating costs. A Whole Building Lifecycle Assessment can bedeveloped to 'Carbon Optimize' the structure and enclosure, reducing its embodied carbon footprint.
