Influence of Concrete Compressive Strength on the Arching Behaviour of Reinforced Concrete Beam Assemblages

摘要

The influence of concrete compressive strength on the loading capacity of purely flexural RC members is minor; however, the beneficial effect of concrete compressive strength on the ultimate loading capacity of axially restrained RC beams can be fairly significant due to development of compressive arch action. Accordingly, in this study, six 2/5th scale restrained RC beam assemblages with various concrete compressive strength (ranging from 18 MPa to 67 MPa) and two different longitudinal steel b
