In order to investigate the effects of bolt-hole arrangement and edge distance of bolted joints on the ultimate tensile strength of joint plates and failure modes, we conduct tension tests of the steel plates jointed with high-strength bolts. We propose formulas to predict the ultimate strength of the joint plates for three failure modes: net section fracture, tearing fracture and end fracture. The experimental results confirm the validity of the formulas. In addition, the experimental results are compared with the design values specified in the "Standard for Limit State Design of Steel Structure (draft)" (Architectural Institute of Japan) and the "Load and Resistance Factor Design Specification for Structural Steel Buildings" (American Institute of Steel Construction). Furthermore, relationships between the failure modes and the geometric properties of the bolt-hole arrangements are clarified: In the tests, three types of steels of 400MPa-grade steel, 590MPa-grade and 780MPa-grade high-quality steels are adopted.
