Specialist Expertise >JDH Consulting has special expertise at an international level in: Wind 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 and wind loads, measurement of fluctuating pressures, development of wind loading codes, standards and design guides, fatigue life calculations. >The JDH methodology for equivalent static wind load distributions This approach 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 stadium. Television and communication towers, especially where the addition of new antennas has required a re-assessment of wind loads. >JDH Consulting methodology for fatigue life under wind loading : > Application of the multi-sector method (originally publshed in a paper by John Holmes in 1991)to predict wind loads and wind load effects, as an alternative to the use of the ‘direction multipliers’ in AS/NZS 1170.2. The multi-sector will produce lower predictions of extreme wind loads thatn the more conservative approach of the Standard, particularly for structures for which the wind load parameters vary greatly with wind direction, such as ground-mounted solar panels and towers on complex topography.
