Joint presentation with NZ Concrete Society
When - Tuesday 15 July 2014
Abstract
Deficiencies in the shear design of concrete structures are inherently more dangerous than deficiencies in flexural design because shear failures can occur with no prior warning and with no possibility for redistribution of internal forces. While accurate assessment of the shear capacity of a reinforced concrete structure is critically important for public safety, the traditional techniques available for this task are open to dispute. For determining flexural capacity engineers can use the simple, accurate, general and internationally accepted “plane sections theory”. However, for finding shear strength engineers typically rely on restricted empirical equations whose applicability and accuracy are sometimes very questionable. In this presentation research aimed at understanding the basic mechanisms of shear transfer is summarised and simple, rational and general shear design and evaluation procedures are introduced.

About the presenter
Professor of Civil Engineering at the University of Toronto, Michael Collins has made outstanding contributions to the field of structural engineering as an educator, researcher and consulting teaching acumen has garnered him many awards including the Canadian Medal for Distinction in Engineering Education. His analytical and experimental research contributions on the shear behaviour of reinforced concrete and particularly his Modified Compression Field Theory have received international recognition and have been incorporated into the design specifications of Canadian, American and European Standards. He has authored or co-authored two books and written chapters in nine further books.
