RESEARCH OF THE FATIGUE LIFE OF PIPING BRIDGE IN WIND ENVIRONMENT
Piping bridge is a way oil and gas pipeline crossing the rivers or channels. For piping bridge, wind load is one of the main loads leading to the failure. The rigidity of the piping bridge is usually more weak than that of bridge, and the amplitude of the piping bridge may change among a large range when the speed of the wind changes. The fatigue life of the piping bridge in wind environment is usually calculated by the fatigue load in average speed of the wind by statistics during a certain time, but when the speed of the wind varies seriously in the fatigue process, the fatigue life calculated by average load may not match the reality. In this article a new method is introduced, the fatigue loads of the piping bridge is simulated by math software based on real wind speed during a period and the fatigue life of the piping bridge is calculated by the simulated loads.
