    Behaviour of Eccentric Concrete Columns Reinforced

    2019-7-22 · The use of steel bars as reinforcement is not preferred in some concrete structures because steel causes corrosion or electric magnetic field problems. One of the best alternatives to steel bars is carbon fibre-reinforced polymer (CFRP) bars. The experimental program consisted of 18 reinforced rectangular concrete columns under different eccentric loadings.

    Minimum and Maximum reinforcement in beams?

    As the use of more reinforcement will not help the structure to be safe as the concrete will fail under crushing. As per IS:456 2000, the maximum area of tension reinforcement should not be more than 0.04bD. where b and D is the breadth and overall depth of the section.

    Minimum and maximum reinforcement in column?

    We all are aware that reinforcement (steel) is a costlier material compared to concrete, so it is better to use it efficiently as more reinforcement will not help the structure be safe as the concrete will fail under crushing. According to IS: 456 2000, longitudinal reinforcement shall not be more than 6 % of the column’s gross cross section.
