The NBCC is employed daily by engineers to define wind and snow loading for structural design. While the obvious intent of the code equations is to allow for the safe design of buildings throughout Canada, a strict application of the code is not necessarily synonymous with an optimized structural design for the control of snow and wind loads. In many situations the code may not accurately account for the influences that the surrounding terrain, neighboring existing buildings, and unique climatic conditions may have on design loads.
The objectives of the presentation will be to identify areas within the code, and the situations in which it is applied, that may lead to over and/or under-predictions of wind and snow loads. Furthermore, we will also discuss alternative analysis tools accepted by the NBCC, such a wind tunnel modeling, water flume modeling, and finite area element modeling, which are available to engineers to refine the design loads for wind and snow. Case studies will be presented to highlight the benefits that may be achieved on projects from the completion of detailed studies. Alternative solutions for the control of wind loads (and for pedestrian-induced vibrations) through the use of tuned mass dampers will also be discussed.
