Database-Assisted Design for High-Rise Structures in Mixed Extreme Wind Climates



Dong Hun Yeo


The use of the DAD methodology in conjunction with multiple wind climatological databases was developed in this study to estimate peak wind effects induced by mixed extreme wind cli-mates, such as hurricanes and thunderstorms. First, we generated synthetic data sets of direction-al wind speeds for hurricanes and thunderstorms for time periods of up to 5000 years. The climatological databases were then used in the DAD methodology to estimate the wind effects under the mixed wind climate for a 60-story reinforced concrete building, known as the CAARC building, assumed to be built near Newark, New Jersey. Results showed that wind effects for serviceability evaluation, that is, interstory drifts and ac-celerations, are significantly affected by mixed wind climates. For a 10-year MRI, the interstory drift and accelerations are increased by 37 % and 49 %, respectively, with respect to those due to hurricanes only. However, Demand to Capacity Indexes (DCIs) were unaffected by the contribu-tion of thunderstorm winds. Wind effects under mixed wind climates depend on the nature of the extreme wind storms, the location and orientation of a building, the building shape, and the building’s structural prop-erties. This study shows the importance of accounting for the mixed wind climate when assessing serviceability. Therefore, for mean recurrence intervals relevant to design for serviceability it is suggested that future standards provide wind speed data for both hurricane and non-hurricane wind speeds.
