FRP-confined concrete under axial cyclic compression

Axial compressive behavior of FRP-confined concrete: Experimental test database and a new design-oriented model

“…Only a small number of studies [10,26,27] reported the FRP properties obtained from ringsplitting tests, and the majority of the studies provided the properties obtained from flat coupon tests or supplied by manufacturers. As for the FRP properties obtained from flat coupon tests, in some of the studies [18,[28][29][30][31][32][33][34][35][36] the elastic moduli (E frp ) and tensile stresses (f frp ) were calculated based on nominal fiber thickness instead of the measured thickness of flat FRP coupons. The datasets from these studies are marked with the superscript 't' in Tables 3 to 7.…”

Behavior of FRP-Confined Normal- and High-Strength Concrete under Cyclic Axial Compression

“…The residual plastic strain of concrete can be defined as the residual axial strain of 25 the material when it is unloaded to the zero stress (Lam et al 2006). Accurate determination of the 26 plastic strains is of vital importance for the overall performance of cyclic axial stress-strain models.…”

A review of FRP strengthened concrete structures under extreme loading

“…The envelop extracted from the stressstrain curves of FRP wrapping columns under cyclic axial compression is close to the stress-strain response of monotonically loaded FRP wrapping columns (Lam et al 2006, Abbasnia and Ziaadiny 2010, Ozbakkaloglu and Akin 2012, Wang et al 2012. When a column is subjected to seismic loading, its energy absorption capacity, rather than its load capacity is the main concern.…”
