Notes:

1. Beam loads are given in total uniform load (W Lbs) not uniform load (w lbs/ft or w lbs/in).

2. Beam loads are based on a simple span and assumed to be adequately laterally braced. Unbraced spans can reduce beam load carrying capacity. Refer to the linked page for reduction factors for unbraced lengths from 2 to 20 feet.

3. For pierced channel, multiply beam loads by the following factor:

• "KO" Series .......95%
• "T" Series ..........85%
• "HS" Series .......90%
• "SL" Series ........85%
• "H3" Series ........90%
• "DS" Series ........70%

4. Deduct channel weight from the beam loads.

5. For concentrated midspan point loads, multiply beam loads by 50% and the corresponding deflection by 80%. Follow this link for information regarding other load conditions.

6. All beam loads are for bending about Axis 1-1.

Sample calculation #1:

Here is a sample calculation to demonstrate the beam loading charts, and the load reduction factors.

Say we have an 6’ span of P1000sl, and want to see what the load capacity is for a point load.

Per the charts, P1000 is good for a maximum allowable uniform load (not load per foot) of 560 lbs. In referencing the notes below, we have the following load reductions:

- X .85 for the sl

- X .5 for a point load in the center

- X .78 load reduction per page 56

Therefore 560 lbs x .85 x .5 x .78 = 185 lbs.

Sample Calculation #2.

Say we have a 5’ span of P1001, and want to see the load capacity for a point load.

Per the charts, p1001 is good for a maximum allowable uniform load (not load per foot) of 1,910 lbs. In referencing the notes below, we have the following load reductions:

- X .5 for a point load in the center

- X .97 load reduction

Therefore 1,910 lbs x .5 x. 97 = 926 lbs.

Note that these assume that the strut connection is able to handle the load. It is the responsibility of you and your Engineer to review all calculations and connections, and to verify that all items are installed per Unistrut requirements. Unistrut Service Company takes no responsibility for the misuse of information provided. Local codes may dictate more stringent requirements.
