Evaluation of Bridges' Maintenance Systems Alternatives Using Value Engineering In Developing Countries (Case Study)

摘要

The maintenance and strengthening of reinforced concrete bridges operations considered one ofthe most important factors that enlarge the whole life of the bridge, as well as reduce the risk of accidents on thebridges and roads. Thus the objective of this paper is to determine the most appropriate repair andstrengthening methods, using the Value Engineering concepts, which is used for comparing the differentcolumns, beams strengthening and slabs topping methods, for achieving the required basic function afterconsidering the main significant factors and without affecting the desired quality. Value Engineering is anorganized process that has been effectively used by a wide range of companies and establishments to achievefunction improvement, time reduction, and improving performance. The potential use of the VE process can beused effectively in developing the optimum maintenance systems of bridges finding that the appropriatealternative in reinforced concrete beams strengthening method was Carbon Fiber Reinforced Polymer Jacket,and Topping with High Strength Concrete is the appropriate alternative in slabs topping system in reinforcedconcrete bridges.
