RED
Consultants Limited has been established since 2004.
Currently, it owns two atmospheric
boundary layer type wind tunnels in Hong Kong and is
currently the sole commercial laboratory in Hong Kong providing wind
tunnel testing services for buildings. Each of the wind
tunnel is about 39m long, with a test section of about 35m long, 5.4m
wide and 3m high.
All of the key
staff of the RED Consultants Limited have Ph.D in civil/mechanical
engineering and have considerable experience in undertaking
wind tunnel test projects, which include wind load and wind pressure
studies on Cyberport Residential Development Stage 12 (RV), MGM Grand
Hotel, Hysan Place, Century Gateway and The Wings; environmental wind
study on Galaxy Resort and Casino, The Wing, Sludge Treatment
Facilities in Tuen Mun and Centennial Campus of the
University of Hong Kong; and many other projects
ADVANTAGES OF CONDUCTING WIND
TUNNEL TESTS
For a safe, effective and economical design of
tall buildings, an accurate determination of wind loadings on the
buildings is essential. Even though design wind loads can be found in
the wind code issued by Buildings Department, they are generally
conservative.
By conducting wind tunnel tests, the effects of
topography, surrounding buildings, building shape and dynamic response
of the building on wind flow characteristics can be investigated. As
nearly all the factors affecting the wind loads on buildings will be
taken account in the wind tunnel tests, it is not essential to use the
conservative design wind loads specified in the wind code. The use of
more accurate design wind loads based on the information obtained in
wind tunnel tests is desirable.
TESTING METHODOLOGY
Two models, namely Topographic model and
Proximity model, will be constructed to investigate wind loads and wind
pressures on the study building. The scaled wind speed will then be
applied onto the structure being studied and relevant data are then
measured.
The Topographic model will
generally be constructed to a
scale of 1:4,000, covering the area within about 5km radius of the
building site, to study the topographic effects on the wind approaching
to the building.
The
Proximity model will generally be
constructed at a scale of 1:400, including
all existing buildings and geographical features located
within a 500m radius of the building site, to study the wind loads and
wind pressures acted on the building under the approaching wind
profiles investigated by the Topographic model study.
In the studies, the
wind profiles will be simulated
by placing different grids, spires and roughness elements in the wind
tunnel. The velocity profile and
turbulence of the wind generated will be measured by a hot-wire
anemometer and the wind loads and pressures on the building model will
be measured by a High Frequency Force Balance (HFFB) and a high
frequency pressure scanner. The corresponding wind loads and wind
pressures on the prototype building can then be calculated by using the
measured data, the structural properties of the building, the
historical wind climate of the city at where the building site is
located, and appropriate mathematical formula.
