Overview

We provided advanced structural analysis, design concepts and construction supervision for the fabric roof structure of the 80,000-seat Shanghai Stadium. The stadium, which features the world’s longest cantilevered-steel-truss roof structure, hosts track-and-field events and soccer matches, as well as cultural and sports extravaganzas.

Fabric Roof and Flying-Mast Structure
Our team provided structural engineering for the fabric roof, a fast-track design-build portion of the project that was erected in less than three months. Our team used tensegrity concepts to design the long-span fabric roof, the first built in China.

The roof, which consists of a continuous series of umbrellas supported by flying masts, rises and dips as it makes its circuit around the field, following the elevation of the back of the stands. Large steel trusses cantilever as much as 73 meters over the stands and divide the roof into 32 trapezoidal bays. The fabric covering consists of 28,900 square meters of Teflon-coated fiberglass – in 17 panel configurations – inserted into the bays.

In addition to providing structural design and construction supervision for the fabric roof, we reviewed the main steel-truss roof framing structure and performed dynamic analysis to determine mode shapes. Our team provided this information to RWDI, who performed a wind tunnel study on the roof structure and a wind environmental study for the field.
