1.4 		PERFORMANCE REQUIREMENTS
A.		General:  Handrails and railings shall withstand structural loading as determined by allowable design working stresses of materials.
B.		Structural Performance:  Provide handrails and railings capable of withstanding the following structural loads without exceeding allowable design working stress of materials for handrails, railings, anchors and connections:

a.		Concentrated load of 200 lbf (0.89kN) applied at any point and in any direction.
b.		Uniform load of 50 lbf-ft. (0.07kN-m) applied horizontally and concurrently with uniform load of 100 lbf-ft. (0.14kN-m) applied vertically downward.
c.		Concentrated and uniform loads above need not be assumed to act concurrently.
2.		Handrails Not Serving As Top Rails:  Shall withstand the following loads:
a.		Concentrated load of 200 lbf (0.89kN) applied at any point and in any direction
b.		Uniform load of 50 lbf-ft. (0.07kN-m) applied in any direction
c.		Concentrated and uniform loads above need not be assumed to act concurrently.
3.		Guards Infill Area:  Shall withstand the following loads:
a.		Concentrated horizontal load of 200 lbf (0.89 kN) applied to a 1sq. ft. at any point in system, including panels, intermediate rails, balusters, or other elements composing infill area.  Loads need not be assumed to act concurrently, with loads on top rails in determining stress on guard.
C.		Thermal Movements:  Design handrails and railings to allow for movements resulting from 120 degree F (49 C) changes in ambient and 180 degree F (82 C) surface temperatures.  Base engineering calculation on surface temperatures of materials due to both solar heat gain and nighttimes-sky heat loss.
