RE: Fence Panel Evaluation

[Subject Prev][Subject Next][Thread Prev][Thread Next]
My $0.02 worth.

In Canada we have CSA S157 with relevant equations for capacities etc and 
ASTM has aluminum standards ...?

Except for weld-heat impact, the equations are similar (not identical) to 
those for steel and other homogeneous isotropic materials.  So you could use 
 Mr=.9*S*Fy and use Fy = 1/2 the specified strength ... etc

Single anchor at bottom seems a little light ...?  And I didn't think 6061 
alloy came with 'T5' temper ... my data book shows 'T4' and 'T6' but that 
might be Canada ...

I'd check that the 5052 alloy works, especially with the reductions if welded. 
 It's used more for architectural work than structural but it might be enough.

Subject: [SEAINT-SEAOSC] Fence Panel Evaluation

Hello All

I have been asked to evaluate the fence structure.

Each Fence panel is 11’-0” tall x 6’-0” wide. Frame is constructed 
with 2x6x.25 Alum 6061-T5 material.

The infill is .125” Alum 5052 cut in a decorative pattern with 60% openings. 

The  frame is supported on a single ¾” dia centered in panel at top & 
bottom, with the bottom a mounting bracket within the 2x6 tube.

Frame weight is 280lbs.

I see I can check the moment in the bottom tube cantilevered from the support 
 bracket and the wind load on the side frames and bottom frame.

Where do I find the equations for Aluminum ?
