Wimbledon Centre Court Moving Roof Structural Design

Geodome Ltd was tasked with development by means of Finite Element Analysis and CAD simulations of Wimbledon Centre Court moving roof trusses.

The principal tasks involved both Static Linear Analysis and scaled model construction. The scaled model enabled visualisation of the movement of the trusses when operated by means of the End-Arms. The End-Arms can be seen at the end of the trusses in the accompanying images.

The Research and analysis effort culminated in a series of CAD and physical models that enabled the design of the final structure of the truss moving assemblies.

Steel Frames

Geodome had been involved with the design of a variety of steel framed structures including: Commercial Buildings, Pressure vessel supports, Floating structures, Off-Shore Jacket structures and Domestic Buildings. The following images demonstrate some of these projects.

Structural Innovation

The Modular Composite Geodesic Dome

Geodome Ltd had developed a modular Geodesic Dome, funded by a DTI SMART and SPUR awards.

The frameless structure was composed of a series of inter-locking modular Structurally Insulated Panels (SIP) that enabled both rapid assembly and high thermal efficiency.

A 5.5m diameter technology demonstrator was erected at Kingston University.

Development and Testing of Structural Joints

Several structural joints were developed by Geodome for application in modular panel systems.

As part of this R&D effort, tensile tests were conducted on interconnecting Structurally Insulated Panels that comprised of alloy extrusions bonded to glass fibre skins, with Polystyrene cores.

Results demonstrated the high capacity that a bonded joint could develop. The design was incorporated in the Geodesic Dome technology demonstrator.

Low Rise Building Design and Alterations

Geodome has provided Design and Analysis services for domestic and low rise structures, including:

  • Conceptual 3D CAD design
  • Generating drawings for Full Plans application
  • Generating structural calculations and drawings for full Plans application
  • Management services

Conceptual Designs

Geodome had been invoved with the conceptual development of several new structural designs, ranging from domes to a variety of foot bridges.

The conceptual designs were generated in CAD and then subjected to FEA. In some cases, 3D rapid-Prototype models were built from the CAD models, for better visualization of the emerging product.

Floating Foot bridge

In order to maintain navigable height over the river thames, a floating foot bridge was conceptually designed.

Foot Bridges

Several conceptual foot bridges had been designed, including stressed skin and traditional steel framed structures.

Railway Foot-Bridge

Tree-Foot Bridge

A stressed skin foot bridge consisting of a series of large steel Hemispheres was designed and analised by means of FEA. The hemispheres were designed to accommodate trees in order to maintian a natural continuation between parks either side of the bridge.

Geodesic Structures

A geodesic Bat-home was desigened for entry into a RIBA competition. The essence was to allow visitors to observe the bats habitat from within.

CFD Simulations and Environmental Analysis

Environmental modelling of buildings, heat transfer and assessment of ‘U-values’ have been determined for a variety of building forms. These include cavity walls, thermal bridging effects and internal and external flow around buildings and within pipes and ducts.
