Technical Details
The building is divided into two parts. The first part houses the gymnasium while the second includes the fitness studio, dojo ring, and administrative offices.
Two large truss beams with a wooden lattice, also known as mashrabiya style, are placed at the height of the vertical window panels, allowing for natural light throughout the gymnasium. The beams include a clear span of 44.80 m (147 ft) over the gymnasium auditorium. The upper and lower truss chords are CLS 200 mm x 800 mm (25.82 in x 103.34 in) beams oriented flat, while the truss web includes CLS 140 mm x 200 mm (5.51 in x 7.87 in) compression members and two 140 mm x 140 mm (18.07 in x 18.07 in) tension and diagonal members. This optimal truss configuration gradually distributes the internal forces with the appropriate stiffness, meaning additional stiffness at the supports and reduced stiffness near the mid-span. The diamond-shaped frame allows natural filtration of daylight.
Project Design Engineers and Calculation Tools
The engineering company Arborescence, in collaboration with the engineering company CBS-CBT, utilized RFEM to analyze the structure and RF-DYNAM Pro to perform the seismic analysis.
