This study proposes a framework on how to construct a simplified model to assess the post-fire cyclic behaviour of such columns. Emphasis is given to the development of simplified material models which can be used to describe the performance of the confined concrete, as its post-fire behaviour is not well studied. The model\u2019s performance is validated against the experimental results of a square, non-seismically designed RC column. Three scenarios are considered. The reference scenario, where the column is exposed only to cyclic loading. In the other two, the column is firstly exposed to an ISO-834 time\u2013temperature curves in a furnace of 30\u00a0min and 90\u00a0min duration and after it cooled down, it is exposed to cyclic loading. The results showed that simplified material models can be used to capture the post-fire cyclic behaviour of an RC column, built without seismic design. It was also found that the confined model adopted played an important role after the peak strength is reached.<\/jats:p>","DOI":"10.1038\/s41598-022-13188-z","type":"journal-article","created":{"date-parts":[[2022,5,28]],"date-time":"2022-05-28T09:03:09Z","timestamp":1653728589000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Simplified model for pre-code RC column exposed to fire followed by earthquake"],"prefix":"10.1038","volume":"12","author":[{"given":"Ioanna","family":"Ioannou","sequence":"first","affiliation":[]},{"given":"Tiziana","family":"Rossetto","sequence":"additional","affiliation":[]},{"given":"David","family":"Rush","sequence":"additional","affiliation":[]},{"given":"Jos\u00e9","family":"Melo","sequence":"additional","affiliation":[]}],"member":"297","published-online":{"date-parts":[[2022,5,28]]},"reference":[{"issue":"11","key":"13188_CR1","doi-asserted-by":"publisher","first-page":"04020232","DOI":"10.1061\/(ASCE)ST.1943-541X.0002794","volume":"146","author":"U Demir","year":"2020","unstructured":"Demir, U. et al.
