2308.11.3.3 Openings in Horizontal Diaphragms

Florida Building Code 2014 > 23 Wood > 2308 Conventional Light-Frame Construction > 2308.11 Additional Requirements for Conventional Construction in Seismic Design Category B or C > 2308.11.3 Framing and Connection Details > 2308.11.3.3 Openings in Horizontal Diaphragms
JUMP TO FULL CODE CHAPTER

Openings in horizontal diaphragms with a dimension perpendicular to the joist that is greater than 4 feet (1219 mm) shall be constructed in accordance with the following:

  1. Blocking shall be provided beyond headers.
  2. Metal ties not less than 0.058 inch [1.47 mm (16 galvanized gage)] by 11/2 inches (38 mm) wide with eight 16d common nails on each side of the header-joist intersection shall be provided (see Figure 2308.11.3.3). The metal ties shall have a minimum yield of 33,000 psi (227 MPa).
For SI: 1 inch = 25.4 mm, 1 foot = 304.8 mm.
