Consulting has special expertise at an international level in :
loads on low-rise buildings and large roofs, bridges, lattice towers, communication
structures, transmission line systems, insurance loss models, tropical cyclones
and thunderstorm wind structure, prediction of extreme winds, measurement of
pressures, development of wind loading codes, standards and design guides, fatigue
JDH methodology for equivalent static wind load distributions
has now been applied
to a wide range of structures. For example :
> Many of the roof structures at Homebush,
New South Wales, constructed for the Sydney 2000 Olympic games, including the
main Australia Stadium.
television and communication towers, especially where the addition of new antennas
has required a re-assessment of wind loads.
buildings where an adjustment of wind-tunnel test data is required due to changes
in height, width, frequency etc.
buildings where an optimisation of steel frame design for wind loads is required.
Consulting methodology for fatigue life under wind loading :
fatigue failures under wind loading are uncommon, there have been a number
of cases where this has occurred, under along-wind loading and cross-wind
vibrations. The calculation of damage rates and fatigue life under wind loading
is complex due to the random nature of
the loading and vibrations. For many wind-sensitive structures fatigue calculations
are desirable at the design stage. The
estimation is simple to apply, does not require complicated cycle counting,
has been verified in full-scale studies at the Silsoe Research Institute in
the U.K. It has been applied to several design situations and failure investigations,
for structures such as lighting poles, fins on a high-rise building, television
antennas and utility towers.
