On Al Yas Island, the biggest natural island of the United Arab Emirates, the Ferrari World Theme Park has been built as an amusement and leisure facility.
According to the design concept of Benoy, it includes a Formula 1 fitted circuit, a shopping mall of the size of 3,229,173 ft², condominiums, marinas and also several luxury hotels and two golf courses.
The park was built in two phases – phase 1 was completed in 2009, whereas the second phase was implemented in 2014.
The Ferrari World Theme Park is covered by a vast roof. The entire roof structure with a surface of about 2,098,963 ft² consists of a MERO spatial framework. With a total number of about 170,000 members and 42,200 joints, it is the largest spatial framework ever built.
For the modelling, the entire structure was separated into three substructures:
- Inner core
- Main structure
- Three outer “pincers”
The core consists of a truss structure with 4,025 joints and 13,346 bars. For structural analysis, 15 load cases, 89 load combinations and 2 result combinations were created.
With its overall dimension of 353 x 350 x 43 meters, the main structure is the largest and most demanding part of the structure. 21,433 joints and 87,102 bars represent the structure. Steel tubes of steel grade S 355 with a yield strength of 36 kN/cm² are used as cross-sections. The maximum cross‑section diameter of the steel columns is 1016 mm.
During the modelling of the three identical “pincers”, it was possible to confine the analysis to one of the three structures. Thus, a relatively clearly arranged calculation model made of 5,687 nodes and 22,828 members was developed. 26 load cases, 74 load combinations and 2 result combinations represent the concept for the structural design of the structure.
Structural Analysis & Design
The calculation of a MERO spatial framework is carried out with the usual means of structural analysis for spatial frameworks with hinged joints. The design calculation of the joints and bars is defined by the MERO approval that is based on DIN 18800.
Spatial frameworks are able to activate a biaxial load transfer, if supported appropriately. In comparison to a planar structure, the deformation and forces within the cross‑sections are reduced considerably, thereby providing a light and thus economical system.
Mero-TSK has focused on RSTAB as the structural frame analysis software for years. The Ferrari World Theme Park has been designed with the current version of RSTAB 6, for only with this version the very large amount of bars could be handled. Mero-TSK used specially developed preprocessors for the creation of the geometry and generated the model via DXF files and the RS‑COM interface into the Dlubal Software program for structural frame & truss analysis.
RSTAB includes a broad variety of interfaces. With their help, the CAD originals of other applications can be imported. Similarly the results of the structural calculations can be exported, in design or calculation program, too. Here, the use of data exchange with MS Excel is very common. The open architecture of RSTAB allows to integrate the structural analysis software into the design process efficiently.
The size of the model constituted a particular challenge during this project. Due to the excellent cooperation between Dlubal Software GmbH and the staff of MERO‑TSK, singular difficulties which would have been irrelevant with a regular amount of bars could be solved fast and individually.
