Impact of Non-Synoptic Winds on Building Components
Publication: Forensic Engineering 2022
ABSTRACT
Non-synoptic wind phenomenon, such as tornadoes, waterspouts, thunderstorm downbursts, microbursts, and other local wind phenomenon routinely generate wind speeds and pressures strong enough to create severe damage. Due to the low probability of occurrence, current design codes still do not require all structures to be designed for tornadoes. Building envelope breach by wind-borne debris impact during storms often leads to devastating consequences for the building’s structure, envelope, and interior. Comparing the wind-borne debris regions in the ASCE 7 design wind maps with the highest tornadic gust wind speed isotach indicates that there is little overlap. Consequently, the vast majority of structures designed and built in tornado prone regions do not contain specific measures to prevent against debris strike.
