Abstract: One disadvantage of most available stress–strain models for concrete confined with fiber-reinforced polymer (FRP) composites is that they do not take into consideration the interaction between the internal lateral steel ...

Abstract: The upper limit to the tension reinforcement ratio in flexural RC members is based on the requirement that tension failure as well as sufficient rotation capacity are ensured at ultimate limit state. However, the provisions ...

Abstract: The moment capacity and failure modes of four types of beams with high reinforcement ratios are reported. The tests were planned and conducted in order to examine a quantitative measure that had been proposed to evaluate ...

Abstract: This paper presents relatively simple, analytically derived curves to model the axial and the lateral stress-strain relations of circular concrete columns. The analytical curves describe the full elastoplastic behavior of ...

Abstract: Reinforced concrete columns usually have a minimum amount of transverse steel reinforcement this transverse reinforcement can have non negligible effects on the response of columns retrofitted with fiber-reinforced polymers ...

Abstract: Deficient concrete-bridge columns can be effectively upgraded by bonding on the exterior surface fiber-reinforced polymer composite sheets with the fibers oriented in the columns’ circumferential direction, thus providing ...

Abstract: This paper presents tests that were performed on square large-scale steel-fiber-reinforced high-strength concrete (HSC) columns under concentric compression loading. The experimental program was mainly designed to examine ...
