In this paper, nonlinear dynamic analyses are carried out on 24 buildings designed according to outdated and modern building codes for the cities of Seattle, Washington, and Portland, Oregon. The results indicate that the median collapse capacity of the ductile (post\u20101970) buildings is approximately 40% less when subjected to ground motions from subduction, as compared to crustal earthquakes. Buildings are more susceptible to earthquake\u2010induced collapse when shaken by subduction records (as compared to crustal records of the same intensity) because the subduction motions tend to be longer in duration due to their larger magnitude and the greater source\u2010to\u2010site distance. As a result, subduction earthquakes are shown to contribute to the majority of the collapse risk of the buildings analyzed.<\/jats:p>","DOI":"10.1193\/012114eqs011m","type":"journal-article","created":{"date-parts":[[2014,11,14]],"date-time":"2014-11-14T09:37:42Z","timestamp":1415957862000},"page":"2087-2115","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":51,"title":["Collapse Risk of Buildings in the Pacific Northwest Region due to Subduction Earthquakes"],"prefix":"10.1002","volume":"31","author":[{"given":"Meera","family":"Raghunandan","sequence":"first","affiliation":[{"name":"Indian Institute of Technology Bombay Department of Civil Engineering Mumbai Maharashtra India 400076"}]},{"given":"Abbie B.","family":"Liel","sequence":"additional","affiliation":[{"name":"University of Colorado Boulder ECOT 440, UCB 428 Boulder CO 80309"}]},{"given":"Nicolas","family":"Luco","sequence":"additional","affiliation":[{"name":"U.S. Geological Survey PO Box 25046, MS 966 Denver CO 80225"}]}],"member":"311","published-online":{"date-parts":[[2015,11]]},"reference":[{"key":"e_1_2_10_2_1","unstructured":"AbrahamsonN.GregorN.andAddoK.2015.BCHydro ground motion prediction equations for subduction earthquakes Earthquake Spectra in press (doi:10.1193\/051712EQS188MR)."},{"key":"e_1_2_10_3_1","volume-title":"Building Code Requirements for Structural Concrete","author":"American Concrete Institute (ACI)","year":"2008"},{"key":"e_1_2_10_4_1","volume-title":"Minimum Design Loads for Buildings and Other Structures","author":"American Society of Civil Engineering (ASCE)","year":"2010"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.1785\/0120020156"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.1785\/0120080147"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.1785\/0120060255"},{"key":"e_1_2_10_8_1","doi-asserted-by":"publisher","DOI":"10.1002\/eqe.571"},{"key":"e_1_2_10_9_1","unstructured":"Baradaran ShorakaM.2013.Collapse Assessment of Concrete Buildings: An Application to Non\u2010Ductile Reinforced Concrete Moment Frames Ph.D. Dissertation University of British Columbia Vancouver BC Canada."},{"key":"e_1_2_10_10_1","doi-asserted-by":"publisher","DOI":"10.1080\/13632469.2013.794718"},{"key":"e_1_2_10_11_1","doi-asserted-by":"publisher","DOI":"10.1029\/GL013i006p00593"},{"key":"e_1_2_10_12_1","doi-asserted-by":"publisher","DOI":"10.1080\/13632469909350343"},{"key":"e_1_2_10_13_1","doi-asserted-by":"publisher","DOI":"10.1785\/0120080298"},{"key":"e_1_2_10_14_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.soildyn.2004.10.007"},{"key":"e_1_2_10_15_1","unstructured":"Center for Engineering Strong Motion Data (CESMD) 2012.Strong Motion Data available athttp:\/\/www.strongmotioncenter.org\/."},{"key":"e_1_2_10_16_1","doi-asserted-by":"publisher","DOI":"10.1002\/eqe.1188"},{"key":"e_1_2_10_17_1","unstructured":"ChandramohanR.LinT.BakerJ.
