Several documents have emerged to provide guidance in terms of mathematical modeling, ground motion selection and scaling, and acceptability of results. While there are some significant differences in these documents, one feature in common is that explicit inclusion of accidental torsion in the nonlinear response history analysis is generally not required. One notable exception is ASCE\/SEI 7\u201016\u00a0(2017), which requires performing nonlinear analyses, including accidental torsion when the building has a torsional irregularity. The analysis presented in this paper supports this requirement, but also shows that neglecting accidental torsion in the analysis of torsionally regular buildings can be problematic. Failure to include accidental torsion in nonlinear analysis of torsionally irregular buildings may indicate stable response instead of dynamic instability, or may significantly underpredict deformations and thereby falsely indicate that deformation\u2010based acceptance criteria have been met. Additionally, it is shown that simultaneous application of ground shaking in orthogonal directions is essential, and that the spatial distribution of geometric nonlinearities related to global torsional response must be included directly in the analysis.<\/jats:p>","DOI":"10.1193\/100516eqs169m","type":"journal-article","created":{"date-parts":[[2017,11,10]],"date-time":"2017-11-10T14:20:29Z","timestamp":1510323629000},"page":"21-53","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":8,"title":["The Influence of Accidental Torsion on the Inelastic Dynamic Response of Buildings during Earthquakes"],"prefix":"10.1002","volume":"34","author":[{"given":"Francisco","family":"Flores","sequence":"first","affiliation":[{"name":"Department of Structural &amp; Geotechnical Engineering Pontificia Universidad Catolica de Chile"},{"name":"Department of Civil Engineering University of Cuenca\u2010Ecuador"}]},{"given":"Finley A.","family":"Charney","sequence":"additional","affiliation":[{"name":"Department of Civil &amp; Environmental Engineering Virginia Tech"}]},{"given":"Diego","family":"Lopez\u2010Garcia","sequence":"additional","affiliation":[{"name":"Department of Structural &amp; Geotechnical Engineering Pontificia Universidad Catolica de Chile"},{"name":"National Research Center for Integrated Natural Disaster Management CONICYT FONDAP 15110017 (Chile)"}]}],"member":"311","published-online":{"date-parts":[[2018,2]]},"reference":[{"key":"e_1_2_11_2_1","unstructured":"American Institute for Steel Construction (AISC) 2010.Seismic Provisions for Structural Steel Buildings ANSI\/AISC 341\u201010 Chicago IL 402pp."},{"key":"e_1_2_11_3_1","unstructured":"American Society of Civil Engineers (ASCE) 2007.Seismic Rehabilitation of Existing Buildings ASCE\/SEI 41\u201006 Reston VA 428pp."},{"key":"e_1_2_11_4_1","unstructured":"American Society of Civil Engineers (ASCE) 2011.Minimum Design Loads for Buildings and Other Structures ASCE\/SEI 7\u201010 Reston VA 636pp."},{"key":"e_1_2_11_5_1","unstructured":"American Society of Civil Engineers (ASCE) 2014.Seismic Rehabilitation of Existing Buildings ASCE\/SEI 41\u201013 Reston VA 518pp."},{"key":"e_1_2_11_6_1","unstructured":"American Society of Civil Engineers (ASCE) 2017.Minimum Design Loads for Buildings and Other Structures ASCE\/SEI 7\u201016 Reston VA 800pp."},{"key":"e_1_2_11_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcsr.2014.01.001"},{"key":"e_1_2_11_8_1","volume-title":"Characterizing the Rotational Components of Earthquake Ground Motion (MCEER\u201012\u20100005)","author":"Basu D.","year":"2012"},{"key":"e_1_2_11_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.engstruct.2014.02.038"},{"key":"e_1_2_11_10_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10518-015-9788-0"},{"key":"e_1_2_11_11_1","doi-asserted-by":"publisher","DOI":"10.1002\/eqe.4290230202"},{"key":"e_1_2_11_12_1","doi-asserted-by":"publisher","DOI":"10.1002\/eqe.4290230906"},{"key":"e_1_2_11_13_1","doi-asserted-by":"publisher","DOI":"10.1061\/(ASCE)0733-9445(1996)122:6(597)"},{"key":"e_1_2_11_14_1","doi-asserted-by":"publisher","DOI":"10.1002\/eqe.2375"},{"key":"e_1_2_11_15_1","unstructured":"Federal Emergency Management Agency (FEMA) 2009a.NEHRP Recommended Seismic Provisions for New Buildings and Other Structures FEMA P\u2010750 Washington D.C. 406pp."},{"key":"e_1_2_11_16_1","unstructured":"Federal Emergency Management Agency (FEMA) 2009b.Quantification of Building Seismic Performance Factors FEMA P\u2010695 Washington D.C. 421pp."},{"key":"e_1_2_11_17_1","unstructured":"Federal Emergency Management Agency (FEMA) 2015.NEHRP Recommended Seismic Provisions for New Buildings and Other Structures: Volume I FEMA P\u20101050\u20101 Washington D.C. 555pp."},{"key":"e_1_2_11_18_1","unstructured":"FloresF. 2017.Overlook Topics in Building Codes: Floor Accelerations and Accidental Torsion Ph.D. Dissertation Department of Structural & Geotechnical Engineering Pontificia Universidad Catolica de Chile."},{"key":"e_1_2_11_19_1","unstructured":"FloresF.CharneyF.Lopez\u2010GarciaD. andde laLleraJ.
