Modeling Stress-Strain Relations for FRP-Confined Concrete

FRP로 구속된 콘크리트의 응력-변형률 해석모델

The analytical model capable of predicting stress vs. strain relations for circular FRP-confined concrete in a rational manner is proposed. The underlying idea is that the volumetric expansion due to progressive microcracking is an important measure of the extent of damage in the material microstructure. Various existing analytical models including the proposed were also investigated, and compared each other and with test results.
