Current data storage and computational capabilities
allow the development of a new generation of standards
whose provisions on wind loads can be structured as
knowledge-based systems drawing the requisite
information from large data bases. We show several
examples demonstrating that such provisions could be
significantly more realistic and risk-consistent than
their conventional counterparts, which are of necessity
based on reductive formulas, tables and plots. We point
out the necessary interaction between development of
knowledge-based standard provisions and the acquisition
of aerodynamics and wind climatology data. Finally, we
suggest that in addition to serving structural
designers' needs, knowledge-based standard provisions
could serve the insurance industry as certified hazard
assessment tools that would be more realistic and
dependable than similar tools developed without the
benefit of careful public scruntiny and broad
