It is rather costly and difficult to experimentally evaluate the performance of concrete-filled tubular (CFT) circular steel columns exposed combined axial cyclic lateral loads. This research paper uses nonlinear finite element (NLFEA) technique assess influence using carbon-fiber-reinforced polymer (CFRP) laminates on structural response failure mode damaged-by-sulfate CFT columns. At beginnin...

The objective of this study is to propose the axial load ratio which assure that strengths CFT beam-columns attain full plastic moment. subjected constant vertical and monotonic increasing moment are analyzed maximum obtained, taking gradient ratio, value stability index α, materials width-thickness steel tube as analytical parameter. After examining effects parameters on strength, required con...
