A Study on Nonlinear Analysis of Circular Concrete Beams Confined by Carbon Sheet Tube Using Solid element

Solid Element를 이용한 Carbon Sheet Tube로 구속된 원형 콘크리트 보의 비선형 해석적 연구

The purpose of this study is to investigate analytically the flexural behavior characteristics of Circular concrete beams confined by carbon sheet. Nonlinear analysis method is presented to simulate the structural behavior beam models. The proposed analytical hardening models were considered the confinement effect of concrete and the tensile effect of carbon sheet in tensile region of concrete. Prandtl-Reuss numerical formula was used to nonlinear analysis of finite element models. Comparisons analytical models with experimental data obtained from flexural testing in the laboratory were presented. Analytical and experimental models show similar behavior.
