Aug 13: Main Cable Truss Post

The main cable truss post will be 13 feet (4 m) long and is a tube steel structural column 6" x 6" x 1/2" thick, which weighs 600 pounds.  It's a key element for anchoring the cable truss, which spans 33 feet (10 m) and will support a vaulted roof.  The orientation of the post is critical to avoid eccentric loading.  The location and orientation for the post is shown on the drawing, below. The post is bolted with epoxy to the footing and embedded in concrete in the stem wall with vertical rebar and stirrups.
