Web joist
(OP)
good day to all of you
im designing a building using web joist as a part of roof.
I already have the loads that i need for the joist and found a web joist that suit for this (i used vulcraft).
the problem is, i want to know the properties of the said web joist but i just can't see the geometric sizes that they are gonna use.
can please be anyone of you have some properties of this material?
thank you very much

lets say i chose 20LH01,it only shows that the depth of the joist is 20" but it didn't tell whats the member comprising the 20LH01. Like the top chord and bottom chord used
for the certain joists.
RE: Web joist
is the note on vulcraft manual,4.7 Camber (pg 25) showed the recommended camber for shored?or it is unshored?
thank you very much
RE: Web joist
What bugs me is that I found it years ago, but cannot now. May have been in an older manual I wore out.

The only way you are going to get the proper information is to call manufacturer. Sometimes they are helpful... other times not so much. Good luck.
RE: Web joist
All you can do is estimate sizes, using some simple math and a double angle column capacity table. The manufacturer should be able to tell you what angle size is designed for a particular situation, but my understanding is that the shop can always substitute heavier sections.

i already thought of this because if the manufacturer gave you their properties and sizes, it will limit their job because contractor may be used this to manufacture their own open web joist
