International Residential CodeIRC 2003 Tables R301.4 and R301.5 specify a minimum concentrated live load capacity of 200 lbf for handrails and guardrails. Insert the tables into this slide.
International Building CodeIRC 2000 Section 1712.1 & 1714 specify that: - the “structural unit and connections” shall be tested with a factor of safety of 2.5.
International Building CodeIBC 2000 The published application of these safety code requirements is that: the guardrail post connection must successfully withstand a minimum applied load of 500 lbf (200 lbf X 2.5).
In wood deck construction, there are 4 basic methods used for attaching the rail post: • Rail post bolted or screwed to the rim joist • Wood blocking behind and next to the railing post • Sheet metal plates on top of the joists • Structural metal brackets that provide an attachment in shear to the deck joist
Rail Post bolted to Rim Joist Fails at less than 200 lbf
Wood Blocking for Structural Support Fails at less than 200 lbf
Sheet Metal Plates nailed to Joists • Failed testing at Virginia Tech Wood Products Lab • Not ACQ Compatible
There is only one methodof attachment that is Safety Code Compliant: A Structural Attachment in Shear
