Then the application of FRP in long span bridge is introduced. It is analyzed that how the extremespan can be enlarged when the FRP material is adopted in cable stayed bridge or suspension bridge.
Based on the wind tunnel tests for large span cantilevered flat roof, the distributing characteristics of mean local shape factor and extreme local shape factor of the roof are studied.
Long span transmission tower-line system is a vital lifeline to power system. Exposing in environment, the system must be robust enough to bear destructive force in extreme environmental conditions.
