The proposed methodology considers the non-stationary and non-linear characteristics of seismic signals and utilizes the Hilbert\u2013Huang transform (HHT) to analyse them. The two reported drawbacks of HHT, i.e. the mode mixing phenomenon and the end effects issue, are resolved through the proposed methodology. More specifically, the advantages of the recently introduced complementary ensemble empirical mode decomposition (CEEMD) are exploited in order to eliminate the mode mixing phenomenon. Moreover, the application of the proposed method only to the strong motion duration of the seismic signal assists to overcome the end effects issue. Thirty natural seismic records of different characteristics, such as frequency content, amplitude and duration, are employed as initial seed signals to demonstrate the proposed method. To illustrate the effectiveness of the proposed technique, comparisons with three established methods for generating spectrum-compatible seismic accelerograms are also provided.<\/jats:p>","DOI":"10.1177\/0142331216654533","type":"journal-article","created":{"date-parts":[[2016,7,5]],"date-time":"2016-07-05T22:50:15Z","timestamp":1467759015000},"page":"239-250","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":5,"title":["Artificial accelerograms composition based on the CEEMD"],"prefix":"10.1177","volume":"40","author":[{"given":"Eleni","family":"Vrochidou","sequence":"first","affiliation":[{"name":"Department of Electrical and Computer Engineering, Democritus University of Thrace, GR-67100 Xanthi, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Petros","family":"Alvanitopoulos","sequence":"additional","affiliation":[{"name":"Department of Electrical and Computer Engineering, Democritus University of Thrace, GR-67100 Xanthi, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ioannis","family":"Andreadis","sequence":"additional","affiliation":[{"name":"Department of Electrical and Computer Engineering, Democritus University of Thrace, GR-67100 Xanthi, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anaxagoras","family":"Elenas","sequence":"additional","affiliation":[{"name":"Deparment of Civil Engineering, Democritus University of Thrace, GR-67100 Xanthi, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2016,7,5]]},"reference":[{"key":"bibr1-0142331216654533","first-page":"1","volume":"21","author":"Alvanitopoulos P","year":"2010","journal-title":"IOP Journal of Science Measurements and Technology"},{"key":"bibr2-0142331216654533","doi-asserted-by":"publisher","DOI":"10.1061\/(ASCE)0733-9399(1998)124:10(1142)"},{"key":"bibr3-0142331216654533","doi-asserted-by":"publisher","DOI":"10.1080\/13632469909350338"},{"key":"bibr4-0142331216654533","volume-title":"Probabilistic seismic demand analysis: spectrum matching and design","author":"Carballo JE","year":"2000"},{"key":"bibr5-0142331216654533","volume-title":"Dynamics of Structures: Theory and Applications to Earthquake Engineering","author":"Chopra AK","year":"2001"},{"key":"bibr6-0142331216654533","unstructured":"EC8 (2004) Eurocode 8: Design of structures for earthquake resistance \u2013 part 1: General rules, seismic actions, and rules for buildings."},{"key":"bibr7-0142331216654533","volume-title":"SIMQKE \u2013 a program for artificial motion generation, user\u2019s manual and documentation","author":"Gasparini D","year":"1976"},{"key":"bibr8-0142331216654533","unstructured":"Gelfi P (2012) SIMQKE_GR version 2.7.
