Structural Engineering: RE: IBC Loads for Guard Rail

Assuming you mean guard rails for people, opposed to vehicular.

IBC 2003, section 1607.7.1, paraphrased:

50PLF at top, in any direction, except 1&2 family dwellings and modified to 20 PLF in certain occupancies in areas not accessible to public

1607.7.1.1
200 lbs concentrated load at top in any direction, not simultaneous with other load.

1607.7.1.2
50 lbs over 1 square foot of fillers, not simultaneous with other load.

1607.7.1.3
30% allowable stress increase for ASD

Subject: IBC Loads for Guard Rail

List,

I wonder if anybody can help me. I have a customer who makes composite
plastic and wood guard rails. He's had them evaluated in the US at ICC
Evaluation Services Inc. and the issued report makes reference to the
IBC. However, we don't use the IBC up here in Canada.

Can anybody tell me what the loads and clause numbers are in the IBC for
guard rails for houses or small buildings?

thanks,
Gary
