Design of Multi-Storey Masonry Buildings in Accordance with CSA S304-14


Multi-storey loadbearing masonry structures were once a common occurrence in Canada. Changes to building codes and the adaption of other building materials had all but eliminated the market of multi-storey construction by the early 2000s. Through a coordinated push to modernize masonry design and construction through extensive research and testing, there has been a resurgence of multi-storey loadbearing masonry throughout Ontario with signs of growth in Eastern Canada and elsewhere. This course will focus on the technical challenges to designing multi-storey masonry structures within the context of the 2014 Edition of the CSA S304 design standard and the 2015 National Building Code of Canada.
