EVALUATION OF WIND-INDUCED FATIGUE DAMAGE FOR EXISTING STRUCTURES CONSIDERING DIRECTIONAL EFFECTS

Abstract

In many buildings, especially high rise ones, wind have been major problem by causing vibration as well as fatigue issues resulted from fluctuations of wind in random flowing. When the structures are designed appropriately enough, they are less likely to suffer from damage caused by wind induced fatigue. However, in some cases, the structures are under designed and fatigue damage can cause non negligible damage and components may start fatigue crack initiation when larger stress is concentrated in some parts. And this result in complete or partially failure of components of parts.
