Tocumen International Airport

Since the terminal is located in a high seismicity area, the design employed a performance-based criteria targeting Life Safety performance for Maximum Considered Earthquake (2,475 year) shaking. SGH analyzed the structure for Zone 3 comprising a lateral-force-resisting system with strategically located special reinforced concrete shear walls and special reinforced concrete moment frames, and a long-span roof constructed with tubular steel members framing into large diameter reinforced concrete columns to form composite special moment frames. Highlights of our work include:

• Assessing performance through a nonlinear time history analysis (horizontal and vertical excitation) with explicit hysteretic modeling of the beams, columns, and shear walls
• Coordinating with Foster + Partners to select member sizes satisfying the performance criteria
• Designing the long span roof structure employing design criteria from AISC 360-10 and American Petroleum Institute’s publication for tubular member connection design for offshore structures
• Preparing construction documents for the long span roof structure
• Responding to peer review comments
