EXPERIENCE

More than 45 years’ experience in wind-engineering applications and research. Evaluated over 1000 buildings and structures for wind loads (local cladding pressures and/or frame forces and moments) primarily through wind tunnel testing; evaluated pedestrian wind climate for many of these buildings; measured forces on numerous other structures including towers, stacks, bridges and solar collectors; defined snow loads for many structures; investigated pollutant dispersion from buildings and stacks; determined heat transfer rates from structure surfaces in the wind; helped define siting criteria for wind energy projects as well as wind tunnel and field testing for development of wind turbine technology; developed meteorological analysis procedures for power line rating; developed wind uplift model for asphalt shingles. He has performed forensic investigations of meteorological conditions and wind effects.

Dr. Peterka’s work in wind engineering includes membership on the national committee which writes the wind load provisions of the national wind load standard ASCE 7, development of the non-hurricane gust wind hazard map for the national wind load standard, consulting for the FAA on aircraft wind shear, participation in a National Research Council report to the U.S. Congress on wind damage, and Board of Directors of the Wind Engineering Research Council. Chairman of ASCE 49, an ASCE Standard committee on wind tunnel testing of structures. Research in wind engineering includes statistical characteristics of fluctuating pressures, adjacent building effects, wind flow around and downwind of buildings, natural ventilation, transport of snow and sand, siting criteria for anemometers, wind loads on asphalt shingles. Other experience includes three years experience in development of liquid rocket propulsion systems for the U.S. Army Missile Command.
