1-4 A Study of Analysis of Life-Cycle Cost on Hot-Dip Galvanized Steel bridges
Bridges play a crucial role to connect two places and extend traffic scope of human. Thus, Its an important subject for concerned agency to maintain bridges function and safety following its construction. As we know, Steel bridges show the characteristics of the lightweight, high strength and high ductility. However, the corrosion problem caused by aging of the coating system of steel bridges will affect the structural safety and increase the cost of maintenance at operation stage. Nowadays, many bridges did not meet its design life yet, and had demolished to pay huge cost for repair and replenishment. This is owing to lack of technique or quality at its beginning. This paper describes hot-dip galvanized steel bridges performing as a free maintenance and also discusses how to prevent the deformation of the galvanized fabrications during the period of the planning, design and maintenance of the galvanizing steel bridges. Moreover, offering a comfortable driving environment in the phase of maintenance. In the past, the bridge design unit only concerned what alternative is economic but neglected the after-cost in the bridge life cycle. Steel Bridges expected to apply life cycle concept in bridge engineering aiming to minimum bridges life cycle cost. Therefore, its a major subject to decrease bridges cost in its life cycle.
