Abstract

Abstract

The active control of railway bridge deflection was investigated to reach the goal of micro-deflection. The concept of intelligent prestressed system (IPS) was presented. The configuration and details of IPS were introduced. The Chinese railway post-prestressed concrete standard girder bridge was analysed with finite element analysis method. An effectual and simple control algorithm for IPS was put forward. The results indicate that the ratio of girder span to mid-span deflection can reach 3 200, the highth of girder can be reduced by 10%, it is feasible that the system can regulate the force of cable in real time, and control the deflection of railway girder bridge.
