The developed hybrid sandwich panel is composed of a top face layer of steel-fibre-reinforced self-compacting concrete (FRC), a core of polyurethane (PUR) closed-cell foam, a bottom face sheet, and lateral webs of glass-fibre-reinforced polymer (GFRP). Full-scale experimental tests on the developed sandwich panels were carried out to characterize their short- and long-term (creep) flexural behaviour. The present work includes a detailed description of the developed panels and the experimental programme carried out and presents and discusses the relevant results. The experimental results showed an almost linear behaviour up to failure. The creep tests were carried out for a period of 180 days, using a creep load equal to 20% of its ultimate loading capacity. An average creep coefficient of 0.27 was obtained for this period. The composed creep model used to simulate the sandwich panel\u2019s creep deflections by considering the individual viscoelastic contributions was able to predict the observed structural response with good accuracy.<\/jats:p>","DOI":"10.3390\/ma15072536","type":"journal-article","created":{"date-parts":[[2022,3,30]],"date-time":"2022-03-30T21:28:39Z","timestamp":1648675719000},"page":"2536","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Flexural Creep Response of Hybrid GFRP\u2013FRC Sandwich Panels"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6457-0668","authenticated-orcid":false,"given":"Tiago","family":"Silva","sequence":"first","affiliation":[{"name":"Institute for Sustainability and Innovation in Structural Engineering (ISISE)\/Institute of Science and Innovation for Bio-Sustainability (IB-S), University of Minho, Azur\u00e9m, 4800-058 Guimar\u00e3es, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7341-3971","authenticated-orcid":false,"given":"Lu\u00eds","family":"Correia","sequence":"additional","affiliation":[{"name":"Institute for Sustainability and Innovation in Structural Engineering (ISISE)\/Institute of Science and Innovation for Bio-Sustainability (IB-S), University of Minho, Azur\u00e9m, 4800-058 Guimar\u00e3es, Portugal"}]},{"given":"Mozhdeh","family":"Dehshirizadeh","sequence":"additional","affiliation":[{"name":"Department of Civil Engineering, Yazd University, Yazd 8915818411, Iran"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3048-1290","authenticated-orcid":false,"given":"Jos\u00e9","family":"Sena-Cruz","sequence":"additional","affiliation":[{"name":"Institute for Sustainability and Innovation in Structural Engineering (ISISE)\/Institute of Science and Innovation for Bio-Sustainability (IB-S), University of Minho, Azur\u00e9m, 4800-058 Guimar\u00e3es, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2022,3,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"422","DOI":"10.1061\/(ASCE)CC.1943-5614.0000176","article-title":"Experimental investigation of large-scale cladding sandwich panels under out-of-plane transverse loading for building applications","volume":"15","author":"Sharaf","year":"2011","journal-title":"Compos.
