Abstract

Currently, Ethiopia is undergoing economic transformation and development which requires exporting of local commodities and importing heavy machineries. Reinforced concrete bridges on different routes are sustaining these equipments loads safely. But there are bridges where their design data is not available for some reasons (i.e. construction time and work document).In the absence of such design data, determination of strength capacity of reinforced concrete bridges are difficult and it is a critical problem that currently engineers are facing. E.R.A manual has developed strength evaluation method for bridges where it has its own way of estimating concrete strength, area of reinforcement and yield strength of concrete. But, based on the current condition of bridges approximate method should be developed to obtain construction data thereby determine the strength capacity of Girder bridges. In this study, experimental investigation of reinforced concrete T-Girder bridges will be carried out based on the existing condition of the bridges. For verification of results, similar bridges with detailed design document will be investigated. The results obtained show lesser reinforcement area and yield strength of steel when compared with original data. it is good with regard of safety while determining what amount of load should pass over z bridge.
