Project Description

Cambodia’s largest stadium, with 60,000 seats and a gross internal floor area of 82,400 m2, draws its inspiration from local cultural elements. The whole stadium lies in a circular water system resembling a dragon boat. The application of an innovative cable-stayed tensile structural system allowed for a unique profile and a longer span to be achieved. Climatic conditions and building features were considered for form optimization and material selection, which makes natural ventilation, natural lighting and self-cleaning great features of the stadium.

Judge’s comments

The lightweight cable stayed stadium roof canopy features some clever innovations. 

A cable-stayed tensile structural system, normally associated with bridge design, was created and applied successfully in the design of the canopy with a longitudinal span of 278 m and a cantilever span of 65 m. Through theoretical analysis and model testing, a brand-new construction method for the stay cable with flexible cable net boundary, together with its control standard was proposed and successfully implemented.
An innovative method for connecting the ring cables helped to solve the problem of slipping resistance under large differential cable forces and eased installation whilst improving reliability. 

The impact and influence of the structural engineering on the stadium is evident and serves as a good example of how we as structural engineers can deliver creative solutions which add value.
