摘要: AbstractFiber-reinforced polymer (FRP) composites with a large rupture strain (LRS) (i.e., having an ultimate tensile larger than 5%) are promising jacketing materials for the seismic retrofit of reinforced concrete (RC) columns. These LRS FRPs environmentally friendly as their reinforcing fibers can be made from recycled plastics [e.g., polyethylene terephthalate (PET) bottles]; result, they also cheaper conventional [i.e., carbon FRP (CFRP), glass GFRP (GFRP), and aramid (AFRP)]. This paper presents first-ever study on behavior modeling FRP-confined under cyclic axial compression. Experimental results first presented to examine both envelope compressive stress-strain curve cumulative effect loading cycles. A model is then proposed shown provide close predictions test results. The formed by combining existing monotonic predic...
