Non-synoptic Wind Effects on Buildings: Current Perspectives on Research and Practice
摘要
This paper providesNon-synoptic wind succinct insights into research and practice concerning non-synoptic wind effects on buildings, with a specific focus on recent advancements in the study of tornadoesTornado and downburstsDownbursts. Based on recent research on non-synoptic windsNon-synoptic wind, experimental techniques and models were developed to examine their effects on buildings and structures. These developments have prompted initial efforts toward establishing design provisions in wind standards and codesWind standards and codes of practice. The paper sheds light on some key aspects related to: (1) laboratory modeling techniques used to replicate non-synoptic windNon-synoptic wind fields and derive design pressure coefficientsPressure coefficients; (2) findings from previous experimental studies assessing wind loadsWind loads on low-rise buildings; and (3) development of provisions in current wind codes/standards. Evidently, despite notable developments, the provisions in existing wind codes and standards remain limited to address such challenging environmental conditions with a need for continued research and codificationCodification efforts.
