Abstract

ECP 203[1] recommended two values for the compression steel ratio in rectangular R.C. section. The first ratio is 10 % of main reinforcement steel as a minimum value to contribute in reducing deflection, however the second ratio is 40 % of main reinforcement steel as a maximum value in an attempt to make the section is under reinforced section, however there is no specific definition for these ratios with the different grade of concrete. In this paper the effect of compression steel ratio on the behavior of a simple span R.C. beam such as bridge girder has been studied. Numerical study of R.C bridge girders under static and dynamic loads has been performed taking the effect of changing compression steel ratio with different concrete grades. Moreover the effect of increasing the steel compression ratios on the failure mode and ductility of concrete has been investigated. It is concluded that using high ratio of compression steel has no influence in case of high strength concrete beams compared with the normal strength concrete beams.
