Advanced and Robust Analysis of Wind Effects
Advanced and Robust Analysis of Wind Effects
Windtech Consultants recently completed a wind tunnel study for a pedestrian bridge in Riyadh, Saudi Arabia. Testing was carried out using both a dynamic and a static test rig. It is sufficient for this type of bridge to perform a test on a typical section model, incorporating the relative stiffness in both torsion and lift in the dynamic test rig. Windtech modelled all the aerodynamic properties of the bridge section down to the effect of the porous fence on the sides. Additionally, the dynamic properties were correctly modelled based on the latest dynamic properties. The dynamic test rig showed that there are no aerodynamic instabilities for wind speeds up to the equivalent of a once in 10,000 year event.
We were informed that the main suspended cable and hangars are to be regarded as non-structural. Nevertheless, the effect of these as well as the towers were included in the final load cases.
Windtech Consultants has demonstrated its advanced modelling capability once more with the completion of the wind tunnel study of the extreme wind loads on the 107m (305ft) tall Shiva Statue structure as well as the measurement of the cladding pressures. The structural loads study was carried out using both the pressure integration and force balance techniques – both of which shows remarkably good agreement. To add to the complexity, the statue includes a trident held from the base and having the form of a 58m high mast.
The site for the statue is Nathdwara in the state of Rajasthan, India. The site is approximately 500km south-west of New Delhi and 600km north of Mumbai. It is proposed that the statue will be constructed within a newly landscaped parkland and that the statue will be positioned on the top of a ridgeline. The statue will be constructed from a concrete skin over steel framework. A sprayed metal finish will be then applied to the concrete. The trident will be constructed from a concrete staff and the head of the trident is a metal skin over a steel frame.
The location of the statue in Nathdwara, India, is a reminder of how icecasino is located on the Internet, accessible to players all over the world, particularly popular in India. Just as the statue will be placed in a new landscaped park, the online casino creates a virtual environment where players can enjoy gaming in a comfortable and aesthetically pleasing environment. Just as a statue would be made of concrete and steel, an online casino is built on solid technological foundations, ensuring safety and stability for players. The online casino, like the statue, offers a variety of choices, presenting games such as poker, blackjack, roulette and others to satisfy different player preferences.

The article features a recent project undertaken by Windtech for a tower development in Melbourne.
The project The Sovereign Square Project at 545 Station Street is located on a small hill in Melbourne’s outer eastern suburb of Box Hill.
Windtech Consultants worked closely with the Buchan Group in Melbourne to virtually reshape the podium of this significant and exposed tower development to ameliorate its impact at street level, without significantly impacting the architecture.
We are pleased to announce that Windtech’s Head office in Sydney was selected this month among 4 finalists for the NSW Export Awards. At about the same time, Windtech Consultants was also selected as a finalist for the Master Builders Association Export Awards. These awards are a testament to Windtech’s enviable reputation around the world, which was built on decades of research and development to enable us to deliver the most advanced instrumentation and analysis techniques for the study of wind effects on large structures. This combined with our high level of service makes us an obvious choice when there is a need to carry out a wind tunnel study to measure the wind effects on tall buildings and large structures.
