Joint Wind-Snow Hazard Characterization for Reduced Reference Periods
Publication: Journal of Performance of Constructed Facilities
Volume 28, Issue 1
Abstract
The joint behavior of snow and wind actions on structures becomes relevant for design in many regions of North America. With trends toward performance-based design for loads/actions arising from natural hazards, information is needed on both individual and joint hazards, e.g., at different hazard levels, exceedance probabilities, or mean recurrence intervals. The writers have developed one approach for two hazards that can be well modeled by sparse processes and have also developed recommendations for joint hazard characterization for the case of a full (e.g., 50 years) design life. The present paper shows how these findings can be extended to provide useful information for joint hazard characterization in shorter reference periods. This can be useful, for example, in the design (single or multiobjective) of formwork or other temporary structures in high wind/snow regions.
