Concrete Cylinders Confined by CFRP Sheets Subjected to Cyclic Axial Compressive Load

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.…”

Compressive behavior of concrete-filled FRP tube columns: Assessment of critical column parameters

“…One such application, the 6 concrete-filled FRP tube (CFFT), have received much attention and significant amount of 7 research has been undertaken to investigate several aspects of structural performance of this 8 composite system (e.g. [2][3][4][5][6][7]). Existing studies have demonstrated the ability of CFFTs to 9 develop very high inelastic deformation capacities [4,5,[8][9][10][11]] making them an attractive 10 alternative for the construction of earthquake-resistant high-performance columns.…”

A Design-Oriented Combined Model (7 MPa to 190 MPa) for FRP-Confined Circular Short Columns

“…The current database [1,[4][5][6][7][8]11,12,[21][22][23]41,42,[49][50][51][52][53][54][55][56][57][58][59][60][61][62][63] composed of n = 198 averaged data was updated with n = 40 data [9,10,[22][23][24][25][26]35,64] from the recent literature on HSC, UHSC, and UHPC for the FRP sheet types mentioned above. Meanwhile, UHSC and UHPC strength data in the literature are available up to 113.6 and 188 MPa, respectively.…”

“…FRP confinement through a glass-fiber tube [1][2][3], frequently using carbon [4][5][6][7][8][9][10], sometimes aramid [11,12], and recently basalt [13], recycled plastic [12,14,15], and natural [16] fiber sheets were used in the experimental studies so far. In addition, the confinement with polypropylene ropes [17,18], FRP+steel tube [19], or prestressing at several levels [20] are recent material types and methods.…”
