In order to analyze the behavior of FWSCT confined reinforced concrete columns under axial load and lateral hysteric load, a load-displacement program was written and compiled in VBA developed by the author. With use of this program, the section response of circular concrete columns confined by two types of materials tube can be modeled. Finally, the load-displacement curve can be obtained by the moment -curvature curve and a suitable plastic hinge length. The analysis theories are from Lee (2006) & Tan (2014). Three specimens were built to test the performance of FWSCT confined reinforced concrete columns. One control specimen (only spiral corrugated tube confined, FWSCT-0) and two FWSCT confined reinforced concrete columns with 5 layers (FWSCT-5) and 8 layers (FWSCT-8) of GFRP were test under constant axial load and lateral reverse cyclic load in NCREE conducted by MATS. Two FRP-wrapped spiral corrugated tubes were made in Jubei, Taiwan, and got good quality. Test results showed that specimens FWSCT-0 suffered shear failure, while specimens FWSCT-5 & FWSCT-8 suffered longitudinal steel rupture with story drift up to 8%. It was found that the plastic hinge location was different from past research. After calibrated the experimental data and studied the effects of the plastic hinge position and length, the author found a reasonable way to explain the unusual results and can deal with the problems. Finally the analysis results have good correlation with the test result.24198109 bytesapplication/pdf論文公開時間: 2017/8/20論文使用權限: 同意有償授權(權利金給回饋學校)複合材料圍束混凝土複合材料圍束鋼筋混凝土柱力量-位移函數GFRPConfined concreteRC columnsLoad-displacement analysisthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/278119/1/ntu-104-R02521213-1.pdf
