3.5.1 Engineering

3.5.1.1 Guardrails and handrails shall be designed to resist a single concentrated

load of 200 pounds applied at any point and in any direction at the top of
the guardrail or handrail and to transfer this load through the supports to
the structure.

3.5.1.2 Guardrails shall be designed and constructed to resist a load of 50

pounds per linear foot applied horizontally at the required guardrail height
and a simultaneous load of 100 pounds per linear foot applied vertically
downward at the top of the guardrail.

3.5.1.3 Guardrail infill (pickets, balusters, etc) shall be designed and constructed

to resist a 50 pound concentrated horizontal load applied over a one
square foot area at any point in the system. Note: The loading of 3.5.1.1,
3.5.1.2 and 3.5.1.3 shall not be applied simultaneously.

3.5.1.4 Handrails shall be designed and constructed to resist a load of 50 lbs per

linear foot applied in any direction. Note: The loading conditions of
3.5.1.1 and 3.5.1.4 shall not be applied simultaneously.

3.5.2 Materials

3.5.2.1 All guardrails, handrails and handrail brackets shall be aluminum

construction alloy 6061-T6, 6063-T5 or 6005-T5.

3.5.3 Design

3.5.3.1 Handrail gripping surface shall be smooth and continuous throughout

ramp sections, steps and landings, return to a guard or return to a wall
that is not more than 1/4” from the end of the handrail termination.

3.5.3.2 The upper handrail shall be 1-1/2” diameter tubing. The top of the upper

handrail shall be 36” above the walking surface. Per 2012 IBC Sec.
1012.2 the height of the handrail above the finish surface “shall be
uniform, not less than 34” (864 mm) and not more than 38” (965 mm).”

3.5.3.3 Optional lower handrail shall be 1-1/2 “diameter tubing. The top of the

lower handrail shall be 25” above the walking surface.

3.5.3.4 Guardrails shall form a protective barrier of a minimum of 42” high.

Guardrails shall be designed such that a 4” sphere cannot pass through
any opening.

3.5.3.5 Handrails and guards shall have a mill finish.
