2304.9.2.5 Controlled random pattern.
BC § 2304.9.2.5
The decking shall extend across a minimum of three spans. End joints of pieces within 6 inches (152 mm) of the end joints of the adjacent pieces in either direction shall be separated by at least two intervening courses. In the end bays, each piece shall bear on at least one support. Where an end joint occurs in an end bay, the next piece in the same course shall continue over the first inner support for at least 24 inches (610 mm). The details of the controlled random pattern shall be as specified for each decking material in Section 2304.9.3.3, 2304.9.4.3 or 2304.9.5.3. Decking that cantilevers beyond a support for a horizontal distance greater than 18 inches (457 mm), 24 inches (610 mm) or 36 inches (914 mm) for 2-inch (51 mm), 3-inch (76 mm) and 4-inch (102 mm) nominal thickness decking, respectively, shall comply with the following: 1. The maximum cantilevered length shall be 30 percent of the length of the first adjacent interior span; 2. A structural fascia shall be fastened to each decking piece to maintain a continuous, straight line; and 3. There shall be no endjoints in the decking between the cantilevered end of the decking and the centerline of the first adjacent interior span.
