D6 Eyebars · AISC 360-22

D6.1 Tensile Strength

The available tensile strength of eyebars shall be determined in accordance with Section D2, with $A_{g}$ taken as the gross area of the eyebar body.

For calculation purposes, the width of the body of the eyebar shall not exceed eight times its thickness.

Eyebars shall meet the following requirements:

(a) Eyebars shall be of uniform thickness, without reinforcement at the pin holes, and have circular heads with the periphery concentric with the pin hole.
(b) The radius of transition between the circular head and the eyebar body shall not be less than the head diameter.
(c) The pin diameter shall not be less than seven-eighths times the eyebar body width, and the pin-hole diameter shall not be more than 1/32 in. (1 mm) greater than the pin diameter.
(d) For steels having $F_{y}$ greater than 70 ksi (485 MPa), the hole diameter shall not exceed five times the plate thickness, and the width of the eyebar body shall be reduced accordingly.
(e) A thickness of less than 1/2 in. (13 mm) is permissible only if external nuts are provided to tighten pin plates and filler plates into snug contact.
(f) The width from the hole edge to the plate edge perpendicular to the direction of applied load shall be greater than two-thirds and, for the purpose of calculation, not more than three-fourths times the eyebar body width.
