The SANS 10160:2010 and 2011 contains a set of new loading stipulations (Parts 1 to 8) and introduces substantial changes to the South African structural design paradigm. In particular Part 3: Wind actions, constitutes a significant departure from the old wind loading procedures included in SANS 10160-1989 which was largely based on the 1952 guidelines of the British CP3 Standard.
This seminar is dedicated to the wind loading aspects of structural design in view of the: • complexity of the related physical phenomena which determine the wind loading,• their numerical interpretation and design simplifications,• the multitude of modern design forms within the built environment, with• structures becoming more prone wind action due to the extensive use of light-weight materials.
The seminar will provide background information and equip the designer with a better understanding, guidance and ability to make informed design assumptions and choices.
SEMINAR OBJECTIVE
SEMINAR FOCAL POINTSThe focus will be on:• The physical process of wind generation• An overview of wind damage in South Africa• Historical development of wind loading stipulations,• Wind climate of SA and its statistical interpretation, including the new wind map• Influence of terrain roughness, topography and immediate surroundings,• Pressure and force coefficients;• Comments on dynamic effects and wind-tunnel technology• A comparison of the previous to latest revision of SANS10160-3• Demonstration of free software to aid in the wind load calculations according to the latest revision of SANS10160-3, with the aim to shorten the gap between coderequirements and input to other structural analysis software or hand calculations
Furthermore, extensive design examples will be provided and the calculations explained.

Demonstration of free softwareThe new SANS 10160-3 provides greater detail and more options, but increased the calculation burden. This software will help.
Adam Goliger of the Council for Scienti-fic and Industrial Research (CSIR) specialised in Wind Engineering and Building Aerodynamics for nearly 30 years.
His vast experience include numerous research investigations, consulting and wind-tunnel testing related to various building and industrial developments in South Africa, wind damage analyses, development of local and international wind design standards, presentations, lectures and participation in several international committees
PRESENTERS
Dr Adam GoligerAnton van Dyk has 20 years experience in design and analysis aspects of structural engineering in the petro-chemical and industrial environment.
A keen interest in computer programming has led him to the development of several in-house software solutions over the years. He is the author of the software “Design Tool for SANS 10160”.
Mr Anton van Dyk (PrEng)Johan Retief is Emeritis Professor at the University of Stellenbosch. His supervision of post-graduate studies in wind engineering over the past decade led to significant advances in the development of statistical- and probabilistic wind load models for South Africa.
He is responsible for the calibration of the new wind map in collaboration with Dr. Adam Goliger of the CSIR and Dr. Andries Kruger of the South African Weather Service.
He was a driving force behind the successful revision of SANS 10160.
Prof Johan RetiefCeleste Viljoen is a senior lecturer at the University of Stellenbosch, where she heads the Structural Risk and Reliability research group. The group specialises in the assessment of the reliability of various structural standard provisions, including wind loads.
She is widely involved in structural standardisation, being a member of the SABS Technical Commitee for Concrete Structures, convenor of the SANS 10100-3 working group and a member of the International Joint Committee on Structural Safety.
