Abstract
Steel moment frames in high seismic regions such as California are often designed to resist fracture. This is accomplished by minimizing flaws and cracks in critical regions of the structure, and through the use of toughness rated materials. However, recent simulations show that especially in high rise structures, wind-induced vibrations may contribute to the growth of fatigue cracks that reduce structural reliability during a seismic event. A series of interconnected experimental and simulation studies are presented. These include scaled flume tests of a representative building, which are then combined with structural models of a high rise building to examine the potential for fatigue crack growth, and quantify its impact on structural reliability. Implications for existing and new buildings are discussed, along with strategies for mitigation
