Abstract:Modern technologies for plasma cutting have the potential to produce bolt holes that perform on a par with those made by currently accepted methods and at the same time to reduce fabrication costs related to steel bridge construction. Current specifications do not allow holes in primary members to be formed by using plasma cutting. A lack of data showing how plasma-cut holes perform under fatigue and tensile loading inhibits their use in secondary members as well. This paper presents findings from an ongoing i… Show more
