摘要

The ladder-core system is a novel structural system for super tall towers that was developed by SOM for the Shenzhen Shum-Yip Tower One. The system features eight mega-columns at the perimeter, forming the vertical rails of the ladders on either side of the core. Composite coupling beams, the ladder rungs, connect the mega-columns with the interior core, creating a comprehensive lateral system. Unlike conventional systems, the ladder-core does not rely on belt trusses, outriggers, or perimeter bracing to achieve tower performance requirements. It improves ductility, redundancy, and uniformity of structural stiffness without conceding open architecture or efficient mechanical routing. Long span beams at each level direct perimeter gravity loads into the mega-columns, eliminating tension produced by overturning moments. By removing complex, heavily reinforced transfer, or outrigger levels, the consistency of the structural system translates into construction speed and quality. For each program stack, the structural elements are integrated with planning modules to create deliberate architectural spaces, from 28.5 m (90 ft) column free spans to 8.5 m (28 ft) cantilevered corners. The composite coupling beams and perimeter beams that are utilized throughout the height of the 400 m (1300 ft) tower are coordinated to allow for a continuous mechanical loop on each floor while maintaining 3.0 m (9.8 ft) clear heights. Cladding module width is also synchronized with architecture and structure geometry utilizing 3.0 m (9.8 ft) wide jumbo vision glass, resulting in a complete, unified delivery of Class A office space to the client. With the client's vision for clear, iconic, world-class office space driving design, the ladder-core system is defined by unobstructed occupant views, simplicity of the floor plate, and inherent structural stability-it exemplifies the seamless integration of building disciplines for an enhanced overall design.
