Experimental study on the method of bridge safety evaluation

Generally, the management criteria by monitoring items applied to the bridge management is decided through the intuition of the based on the empirical data without any professional and systematic background. In this study, the span deflection is selected among the bridge monitoring items and verify the appropriate management criteria in the case of deflection by the laboratory test. Test specimens are the small-sizing bridge specimens which are made by reinforced concrete. Those are classified by variation of span length and stiffness of section. As a result of test, the relationship between the span center deflection and the safety level of bridge is suggested.
