In recent decades, the application of fibre-reinforced polymer (FRP) composites for strengthening structural elements has become an efficient option to meet the increased cyclic loads or repair due to corrosion or fatigue cracking. Hence, the objective of this study is to explore the existing FRP reinforcing techniques to care for fatigue damaged structural steel elements. This study covers the...

In this paper, a three dimensional analysis is performed to investigate the static instability of long-span cable-stayed bridges due to wind loading. Cables made of carbon fiber composite cable (CFCC) are studied. Nonlinearity due to displacement-dependent wind loading is considered. A 1400meter cable-stayed bridge model is used to investigate the static behavior of bridges with both steel and ...

This pctpcr focuses on the use of externally bonded high modulus carbon fiber reinforced polymer (HM CFRP) materials to strengthen steel bridges and st ructures. Proper installation of the CFRP materials is necessary to prevent premature failure due to debondi ng. The paper proposes guidelines and installation techniques based on the best practice reported in the literature and the extensive pr...

Steel bridge has the advantages of large span capacity, fast installation speed, easy transportation, repair and replacement, been widely used in practical engineering. The deck pavement steel is a crucial link whole building cannot be ignored. For long bridge, generally phenomenon fatigue cracking, service life difficult to reach expected life. Laying multi-layered protective layer structure o...
