NettetTraditionally the stiffener width to thickness ratio has been limited to no more than 10 to avoid local buckling. However, the Eurocodes have no restriction on this ratio, and more slender stiffeners are permitted, although checks may need to be made that they will not be at risk from local buckling. NettetThe normal spacing for deck joists is 16 inches on center. Before you build a deck, verify this with your local building department and read the installation instructions for the decking material. Some decking materials installed at a 45-degree angle to the run of the joists require the joist spacing to be 12 inches on center.
