Quick Details

ROOF OF LARGE-SPAN GRID STRUCTURE STADIUM

The Infinite Plaza in Guangzhou, located in Baiyun New City, Baiyun District, Guangzhou, is an iconic modern commercial complex. The project consists of two towers, Tower A and Tower B, which are approximately 60 meters apart. To achieve functional connectivity and architectural aesthetics, a multi-level large-span diagonal pedestrian bridge is set between the two towers:

3rd-floor bridge: 77.9 meters span, 17 meters width, total weight approximately 800 tons.

6th and 7th-floor bridge: 86.4 meters span, 20.5 meters width, total weight approximately 1500 tons.

The bridges utilize a large-span truss structure system, not only achieving efficient spatial connectivity but also becoming a prominent visual focal point of the plaza, showcasing PFM's expertise in complex truss structure engineering.

PROJECT TECHNICAL SOLUTION

Joints & Connections

Steel Truss Diagonal Structure:

Significantly enhances overall stability and load-bearing capacity, meeting the requirements for large-span and high-rise connections.

Material Selection

Main Structure: Q355B steel, known for its strong bending resistance and load-bearing capacity.

Material Selection

Roofing Material: Glass curtain wall combined with steel structure, balancing daylighting, aesthetics, and functionality.

PROJECT HIGHLIGHTS & ADVANTAGES

Super Large Span

Achieves a 86.4-meter column-free span, meeting the functional connectivity needs of two super high-rise buildings.

Structural Stability

The diagonal truss and multi-joint design ensure long-term stability of the bridge under complex loads and wind-induced vibrations.

Efficient Construction

Utilizes segmented prefabrication and overall lifting techniques to minimize construction difficulty and reduce safety risks.

Architectural Landmark

The pedestrian bridge becomes the iconic spatial node of the commercial plaza, enhancing the overall recognition and value of the architectural complex.

Aesthetic & Functional Integration

The combination of glass and steel structure not only ensures structural performance but also adds a modern architectural aesthetic to the bridge.
