A circular web penetration is located at the center-line of the beam depth with a maximum diameter of d/6 unless otherwise noted on the plan or schedule. The minimum clear distance from the support or point load to the center of the opening is specified as d, and the minimum clear distance from the top and bottom of the opening to the beam flange is d/6. The vertical eccentricity of the opening from the beam center-line is limited to d/2 unless noted otherwise.
