Incorporation of additional information into the South African Wind Load Formulation
The South African wind loading standard SANS 10160-3:2019 recently adopted an improved map of characteristic basic wind speeds and increased the wind loading partial safety factor from 1.3 to 1.6. These changes represent an overhaul of the design wind loads throughout South Africa and were the result of several studies on the wind loading standard. Since these studies were conducted, substantially more wind speed data has been made available. This investigation aimed to use this data to assess the current design loads by estimating location-specific design values that maintain the current reliability level of the standard. A statistical test was developed to assess whether the design values in SANS 10160-3:2019 could be supported by the new data. It was found that several updates could be considered. These were incorporated into a new recommended map of basic wind speeds that could be considered for inclusion in the next revision of SANS 10160-3.
期刊介绍:
The Journal of the South African Institution of Civil Engineering publishes peer reviewed papers on all aspects of Civil Engineering relevant to Africa. It is an open access, ISI accredited journal, providing authoritative information not only on current developments, but also – through its back issues – giving access to data on established practices and the construction of existing infrastructure. It is published quarterly and is controlled by a Journal Editorial Panel.
The forerunner of the South African Institution of Civil Engineering was established in 1903 as a learned society aiming to develop technology and to share knowledge for the development of the day. The minutes of the proceedings of the then Cape Society of Civil Engineers mainly contained technical papers presented at the Society''s meetings. Since then, and throughout its long history, during which time it has undergone several name changes, the organisation has continued to publish technical papers in its monthly publication (magazine), until 1993 when it created a separate journal for the publication of technical papers.
