FRP-confined circular concrete-filled steel tubular columns under cyclic axial compression

Cyclic lateral response of FRP-confined circular concrete-filled steel tubular columns

“…These GFRP material properties are taken from the coupon tests presented in Ref. [17] where the same batch of glass fiber sheets was used. The CFRP jacket used had an elastic modulus of 237.8 GPa and an ultimate strain of 0.85%, based on a nominal thickness of 0.34 mm per ply as obtained from five tensile coupon tests following Ref.…”

“…[10][11][12][13][14][15][16]) on the effectiveness of FRP confinement in improving the structural behaviour of CFT columns. The authors' group has conducted a systematic study into the axial compressive behavior of FRP-confiend circular CFT columns; this study included several series of tests on cicular glass FRP (GFRP)-confined CFT columns under monotonic axial compression [6] and cyclic axial compression [17], and the development of monotonic and cyclic stress-strain models for the confined concrete in circular CCFT columns [17,18].…”

Study on Axial Compression Bearing Capacity of Reinforced Concrete Filled Steel Tube Members

“…Extensive studies have been conducted on the static and dynamic analyses, and the fire performance of CFST members [1][2][3][4][5][6][7][8][9][10]. For example, Han et al [1], Yu et al [2], Dundu et al [3], Dai et al [4] studied the compressive strength of CFST members.…”

“…For example, Han et al [1], Yu et al [2], Dundu et al [3], Dai et al [4] studied the compressive strength of CFST members. Han et al [1], Yu et al [5], Prabhu et al [6] investigated the axial compression performance of CFST members encased by various different materials, such as concrete, FRP and CFRP. Wang et al [7] studied the behavior of fire-exposed CFST columns.…”

Experimental investigation of the behavior of aramid fiber reinforced polymer confined concrete subjected to high strain-rate compression

“…Numerous studies, starting with the study by Fardis and Kahalili [1] who conducted axial compressive tests on fiberglass tubes, have verified that the lateral confinement provided by FRP jackets places lateral dilated core concrete into a three-dimensional stress state, which significantly improves the axial compression and dilation behavior [2][3][4][5][6][7][8][9][10].…”
