Effect of Reinforcement ratio to reliability * index of beam

Abstract

This paper presented an effect of reinforcement ratio to Reliability index (P) for beam section at their flexural strength limit state. The flexural strength of the beam sections is mathematically modeled for singly reinforcement and doubly reinforcement. Results of the reliability analysis are presented in terms of the reliability index at various levels of reinforcement ratio. When the ratio of reinforcement ratio per balance reinforcement was increased. the reliability index will be increased until the ratio of reinforcement ratio per balance reinforcement ratio is 0.50. the reliability index will be decreased and when the ratio of Compressive reinforcement ratio per balance reinforcement ratio was increased. the reliability index will be increased too.
