In the 2010 National Building Code of Canada (NRC 2010), certain structures can be designed for seismic loads using an equivalent static force procedure. In these provisions, elastic design forces are reduced by a ductility factor, Rd, which accounts fo...

Summary
This project will involve the modeling of typical multistage buildings and non-linear dynamic analyzes for various seismic hazards (Montreal, Quebec, Charlevoix). The models will be developed using OpenSees, and validated with commercial software (SAFI, SAP2000). The temporal responses of typical buildings, subject to earthquakes generated for the region, will be calculated for different parameters (number of floors, bays, types of SRFS). Pushover type analyzes will also be carried out (rigid frame systems or shear walls). Sectional ductility demands will be evaluated for different types of wood sections and assemblies. These ductility values will be used to target the best wood seismic resistance systems, depending on the type of construction.
Utilizing Linear Dynamic Analysis (LDA) for designing steel and concrete structures has been common practice over the last 25 years. Once preliminary member sizes have been determined for either steel or concrete, building a model for LDA is generally easy as the member sizes and appropriate stiffness...
Recently, Canadian building regulations have allowed construction of light-frame wood buildings up to six storeys. Even though equivalent static force procedure (ESFP) is generally used for the seismic design of such buildings, in cases of irregular structures and in high seismic zones a linear dynamic analysis (LDA) is required by the...
