CABLE FORCE ADJUSTMENT AND CONSTRUCTION CONTROL. IN: BRIDGE ENGINEERING: CONSTRUCTION AND MAINTENANCE

Due to their aesthetic appeal and economic advantages, many cable stayed bridges have been built over the worls in the last century. With the advent of high-strength materials for use in cables and the development of digital computers for the structural analysis and the cantilever construction method, great progress has been made in cable stayed bridges. This paper deals with two topics: cable force adjustment and construction control. The methods for determining the cable forces are discussed, and a presentation of the cable force adjustment is given. A simulation method for a construction process of prestressed concrete cable stayed bridge is illustrated and a construction control system is introduced.
