Example 1: The structural members of a 2-story office Building is required to have a 1-hour fire resistance. Thebuilding is 35 ft. (10.67 m) wide and 60 ft. (18.29m) in length. Repetitive member framing spans from the exteriorwalls to glued laminated beam at the center of the building. Two simply supported beams, each 30 ft. (9.14 m) inlength, bear on the exterior walls and A column at the center of the building. The beam is of Greater depth than thefloor/ceiling system; therefore a Portion of the beam will be left exposed beneath the Rated floor/ceiling assembly.Determine the fire endurance rating of the beam selected to carry the imposed loads. Extreme fiber in bending Fb isgiven 2,400 psi (16.55 MPa), and the species is Douglas fir. The live and dead loads are 50 lb./ft2 (2,394 N/m2) and 15Ib./ft. 2 (718 N/m2), respectively. The load duration Factor, CD, istaken equal to 1.0.
