A custom form-finding script was developed to establish an initial form-found geometry in the Grasshopper environment. Using Geometry Gym, this initial form-found 3D geometry was exported to GSA. GSA covered the final form finding analysis, calculation of cable prestress and design of structural steel members.
The cable drape and pre-stress were rationalised within this workflow to optimise the utilisation of the existing structure and minimise the requirement for local strengthening.
The form-found geometry was used to develop 3D connection models in Rhino. These were used for finite element analysis in Strand7 as well as for the design delivery. We issued the connection design in a 3D format for use in the shop detailers Tekla models.
The design was kept solely within a secure 3D environment. Automation and parametric modelling accelerated design reviews and alterations. The digital collaboration with designers, architects, contractors and builders supported a comprehensive workflow which saw the roof designed in three months and constructed in less than 12 months.
The tensile steel and fabric roof, of approximately 8,000 m2, now provides full coverage over the centre court. It allows play during all-weather events improving conditions for players and spectators.
We have a unique opportunity to make a difference
As our cities reimagine their shape and function during this period of change, there will be opportunity to consider reinvigorating underutilised assets for all to enjoy in the future. Assets could include great sporting venues, commercial buildings or arts and culture institutions.
One thing that’s clear is that we must put sustainability at the heart of our designs. We must think creatively and use the tools available to us to shape a more sustainable and resilient future.
