Discussion about solution to the key problems of application of modern nonmetallic structures in bridge engineering |
| |
Abstract: | The evident advantages and application prospect of the modern nonmetallic structures and the traditional new structure style are discussed base on the characteristics analysis of the nationality and high-tech in bridge engineering,and the crucial requirements on the structures are met in aspects of high strength,longspan,corrosianrce,sistance seismic,stability fatigue,intelligent control and so on,but the rest problems are deformation consistency of FRP composite with concrete and FRP tendon prestressing, FRP tendon anchoring in the prestressed FRP concrete structures and so on. |

Keywords: | bridge modern nonmetallic structures FRP concrete FRP composite materials deformation consistency prestress system |
