Abstract:
This report presents proof of concept for a methodology
pertaining to combined effects of hurricane wind
speed/storm surge height events. The methodology was
developed jointly by the Building and Fire Research
Laboratory (BFRL) of the National Institute of Standards
and Technology (NIST) and the National Weather Service
(NWS) and the Oceanic and Atmospheric Research (OAR) of
the National Oceanic and Atmospheric Administration
(NOAA). Its purpose is to develop site specific,
risk-based design criteria for coastal structures
subjected to the combined effects of hurricane wind
speed and storm surge. The methodology utilizes an
integrative, interdisciplinary approach that
incorporates state-of-the-art knowledge in hurricane
science, hydrology, probabilistic methods, and
structural engineering needs, and involves the following
steps: (1) selection of a stochastic set of hurricane
storm tracks affecting the region of interest, (2)
hydrodynamic simulation of the region of interest using
program SLOSH and the selected storm tracks to generate
time histories of wind speeds and corresponding time
histories of storm surge heights at sites within the
affected region, and (3) use of hurricane wind speed and
storm surge height data generated in Steps (1) and (2)
to develop (a) probabilistic information on joint wind
speed/storm surge height events, and (b) risk-consistent
structural design criteria.
