摘要

南非风荷载标准SANS 10160-3:2019最近采用了一种改进的特征基本风速图,并将风荷载局部安全系数从1.3提高到1.6。这些变化代表了对整个南非设计风荷载的彻底改革,也是对风荷载标准进行多项研究的结果。自从进行这些研究以来,已经提供了更多的风速数据。本次调查旨在利用这些数据,通过估计保持标准当前可靠性水平的特定位置设计值来评估当前设计负荷。制定了一项统计测试,以评估SANS 10160-3:2019中的设计值是否能得到新数据的支持。发现可以考虑进行几次更新。这些被纳入了一个新的基本风速推荐图中,可以考虑将其纳入SANS 10160-3的下一个版本中。

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.
