@article { , title = {Design-oriented models for concrete columns confined by steel-reinforced grout jackets}, abstract = {© 2018 Elsevier Ltd This paper investigates the axial stress–strain response of concrete confined with Steel-Reinforced Grout (SRG) jackets comprising of Ultra High Tensile Strength Steel (UHTSS) textiles embedded in an inorganic binder. Brittle, semi-ductile and ductile stress–strain response curves are identified according to the level of confinement stiffness provided by the SRG jackets. A comprehensive experimental database of 80 SRG-confined columns is developed and used to assess the influence of key design parameters. The results are then used to propose new design-oriented models to predict the strength and ultimate strain of SRG confined concrete columns by taking into account the confinement stiffness of the jackets.}, doi = {10.1016/j.conbuildmat.2018.05.088}, eissn = {1879-0526}, issn = {0950-0618}, journal = {Construction and Building Materials}, pages = {313-326}, publicationstatus = {Published}, publisher = {Elsevier}, url = {https://nottingham-repository.worktribe.com/output/1283575}, volume = {178}, keyword = {Confinement model, Concrete, Steel Fabric, Inorganic matrix, Mortar, SRG Jackets, Seismic strengthening}, year = {2018}, author = {Thermou, Georgia E. and Hajirasouliha, Iman} }
