The beam web slots shall be made using thermal cutting or milling of the slots and holes or by drilling the holes to produce surface roughness in the slots or holes not exceeding 1,000 μin. (25 μm). Gouges and notches that may occur in the cut slots shall be repaired by grinding. The beam web slots shall terminate at thermally cut or drilled 1 1/16-in.- (27-mm-) diameter holes for beams nominal 24 in. (600 mm) deep or greater or 13/16-in.- (21-mm-) diameter holes for beams less than nominal 24 in. (600 mm) deep. The slot widths and tolerances are shown in Figure 14.3. The length of the 1/8 in. (3 mm) slot shall be at least equal to the width of the shear plate but need not exceed half the slot length, . The transition from the 1/8 in. (3 mm) slot to the 1/4 in. (6 mm) slot shall not have a slope greater than 1 vertical to 3 horizontal.
