The Oregon Resilience Plan – Critical and Essential Buildings – February 2013 74 <br /> <br /> <br />Our group also looked beyond the building code to buildings that have functions that we believe are <br />vital to the seismic resilience of the state as a whole. Supermarkets, pharmacies, some big-box retail <br />stores, and banks comprise a subset of buildings that will be relied upon heavily following a disaster. The <br />importance of having an ample supply of basic provisions—such as food, water, medical supplies, and <br />money—in affected areas after a natural disaster has been underscored by many previous events, <br />including Hurricane Katrina and the 2011 Tohoku earthquake and tsunami in Japan. If buildings that <br />house these resources are not seismically resilient, the ability of the community to recover after the <br />event will be adversely affected. For these reasons, the community’s large retail buildings and bank <br />buildings have been classified as critical buildings in this study. <br /> <br />Figure 4.1: Oregon Structural Specialty Code, Table 1604.5 <br />Past earthquakes have brought to light the dangerous nature of unreinforced masonry (URM) and non- <br />ductile concrete structures. Because of their tendency to sustain excessive damage or even collapse in
