A central part of this work has been on the development of a set of Seismic Retrofit Guidelines, which are a performance based tool to provide engineers the basis for retrofit. For the 3rd Edition of guidelines (2016), which includes the new 2015 ground motions from the National Building Code of Canada, there is an increased focus on long duration shaking and their effects. The aim of this study was to investigate the effect of ground motion duration on the collapse probability of wood shearwalls. First several physical tests were performed in which full-scale wood shearwalls were subjected to long duration ground motion. A numerical model was then calibrated to these test results and used to run incremental dynamic analysis using two suites of ground motions including long and short duration. The results indicated that near the code shaking level (ground motions with a 2% in 50 year probability of exceedance) there was little difference between the two record sets. At higher shaking levels, the difference between the two record sets became more apparent, with the median collapse shaking level becoming lower for the long duration suite. At these high shaking levels more damage and cyclic degradation was observed in the models. This implies that while duration has little impact on the collapse capacity of wood shearwalls near code shaking levels, the margin against collapse is significantly lower when this type of system is subjected to long duration motions.
