There are tendencies to design and analyze the reinforced concrete structures by the inelastic theory, because the elastic theory has limitations to explain realistic behaviors of the reinforced concrete.
This study is aimed to knowing the relationships of load - deflection and rotation of reinforced concrete simple beam. The test considers that the influence of the depth of beam and the amount of reinforcement on deflection behavior of beam.
From this study, results are as follows ;
1) The amount of compression reinforcement mainly affects on the slope in descending portion after peak load of the relationships load and deflection.
2) The net tension reinforcement ratio significantly effects the maximum moment and center rotation of flexural members. In case of the net tension reinforcement ratio is same, the maximum moment is Increase with decreasing depth of beam.
3) According to the decreasing net tension reinforcement ratio, the relative rotation of flexural member is decrease.
Finally, the deflection of doubly reinforced beam can be diminished more greatly than singly reinforced beam.
