For the purpose of designing against wind induced fatigue of high rise steel buildings, a series of fatigue tests on welded beam ends at the beam-to-column connections were carried out. Specimens were composed of welded built-up box section steel columns and built-up wide-flange steel beams using 490N/mm^2 class grade of steel. Three types of fabricating methods for beam end joint were examined ; i.e. a field welding type with bolted web and welded flanges , a shop welding type with conventional scallops and another shop welding type without scallop (Non scallop type). Seventeen specimens were prepared for high cycle fatigue tests , low cycle fatigue tests and varying amplitude fatigue tests . S-N diagrams for fatigue design and cumulative damage factors based on Miner's law were obtained and discussed, comparing with the JSSC design recommendation.
