A Study on Development of Monitoring System for Precise Consturction of Large Scale Prestressed Concrete Bridges

PC장대교량의 정밀안전시공을 위한 시공계측관리시스템의 개발에 관한 연구

Recently, the prestressed concrete long-span bridegs are increasingly built at various locations in the world. The mechanical and structural behavior of prestressed concrete bridges is very complex because of nonlinear and time-dependent material behavior and sequential change of structural system due to stepwise construction. These factors may cause construction errors with respect to design value and monitoring system is needed to minimize or to protect construction errors. This study presents the basis development of monitoring system for precise construction of large scale prestressed concrete bridges.
