A Study on the Flexural Behavior of Reinforced High Strength Lightweight Concrete Beams |
| Abstract |
In general, flexural strength and ductility of reinforced concrete beam with stirrup are depend on the compressive strength of concrete and longitudinal steel ratio. In this study, nine reinforced high strength lightweight concrete beams and three reinforced normalweight concrete beams with stirrup were tested to investigate their behavior and to determine their ultimate moment capacity. The variables were the compressive strength of concrete (400, 500kg/cm2) and the ratio of tensile steel content to the balanced steel content (0.22< p /p b<0.56). Test results are presented in terms of load-deflection behavior, ductility index, and cracking patterns. |
