In the Hyogo-ken Nanbu Earthquake (1995), ruptures in the beam end welds near weld access holes were reported. Regarding this damage, countermeasures have been taken to prevent early fracturing by widening the beam end flanges, etc., but existing buildings have many details similar to those that suffered fracture damage. It is important to evaluate deformation capacity of steel beams with weld access hole under cyclic loading.
In this paper, structural test and FE analysis were carried out to investigate the effect of thin beam webs on the deformation capacity of H-shaped beam with weld access hole.
