The present experiment is conducted for studying on maximum strength as tension members by making test specimens that have high strength bolted friction joints of 590N/mm^2 grade high-performance steel developed for building structures. The kinds of test specimens are plate, channel and H-shape steels. Maximum strength of a high strength bolted friction joint at a tension member is caused by a lot of complex factors, e.g., bolt arrangement, net area in stress, section of segment, material property, bolt tension, and so on. Therefore, the point is that how well these factors can be expressed as a simple effective section. Design formulae on maximum strength are proposed at 『Standard for Limit State Design of Steel Structures(draft)』 and 『Recommendations for The Design Fabrication of High Strength Bolted Joints』, however past studies for a local fracture are few, and it is not clear about equivalence between a fracture form and a design formula. The purpose of this paper is to investigate justice about design formulae that are equivalent to difference of a fracture form.
