Abstract


Bridge expansion joints due to the long exposure to the atmosphere and is directly exposed to the impact of vehicle load , so vulnerable to destruction, requires constant maintenance , which affects not only traffic, but also improve the project cost. Although there have been many improvements over the years designed and made ??a lot of better maintenance and repair methods, such as using high performance fiber reinforced concrete , high strength concrete or epoxy coating , but the results achieved in general, there are many defects and insufficient , did not fundamentally solve the problem . In recent years, the emergence of a new cement -based composite materials ---- ECC material , because of its superior crack resistance to deformation, is being a widespread concern in the field of civil engineering . Therefore, this thesis attempts to explore the use of ECC material design flexible deck plate , instead of the conventional telescopic device to meet the needs deformation temperature . Because ECC material has unique properties - excellent crack control ability and good resilience , so use ECC material to build a flexible deck plate , not only to meet the needs of deformation temperature, etc. , can also reduce the appearance of cracks in the bridge structure , improve the durability of bridge structures in the long run but also has good economy. This paper briefly analyzes the reasons for the destruction of traditional telescopic device , design method, and deficiencies ; study of the new bridge connecting structure - ECC deck plate design processes and methods of computation as well as some of the problems faced in calculating their solutions methods ; explores the deck plate ECC ECC construction technology and materials in some of the issues ; and presented on the deck plates of ECC research and application of some of the comments and suggestions. Deck plate not only makes driving smooth and comfortable , but also can improve the durability of the bridge , to prevent water leakage. Same time as the ECC material is a high toughness ductile concrete , has a strong energy absorption capacity , help bridge the seismic . Flexible deck plate instead of the traditional joints , without changing the nature of simply supported beam bridge under the premise to solve the joints and beam end connection interface crack problems exist , very necessary in our application.
