Abstract
Steel plate shear walls have typically been analyzed using quasi static and monotonic pushover analysis; however, dynamic excitations during an earthquake elicit different behaviour from the structure due to the nature of the loading. This report outlines the design and analysis of a steel plate shear wall according to NBCC and S16-09 requirements. For lateral loading, wind and seismic forces are considered. The NBCC recognizes two procedures for determining seismic loading, the equivalent static force procedure and dynamic analysis. An analytical model was created in SAP2000® using capacity design principals and the strip model. The dynamic analysis uses bi-directional tension strips to resist load reversals and was validated against a finite element analysis using ABAQUS®. The dynamic analysis provided an effective means of designing the steel plate shear wall. The equivalent static force procedure resulted in a similar design; however, the structure required stiffening to meet the deflection requirements.
