Truss Tuesday: Will it Bend?

Girder Truss

This week’s truss:

Question: Which member of this hip girder has the highest stress? There are jacks every 2 feet across most of the bottom chord.

Building Code: FBC2020

Loads (psf unless otherwise noted):
TC Live Load 20
TC Dead Load 10
BC Live Load 0
BC Dead Load 10

Wind: 160 mph

The answer will be posted on Thursday!

This is not a production truss! This is simply an example for Truss Tuesday conversation.

Answer: The highest stress occurs at the vault in member B3. The lumber grade would have to be upgraded to Dense Select Structural to handle the bending.
