Today’s blog is video #5 in a series from glulam provider Richland Laminated Columns, covering the finishing touches of the process.
Tune in Tuesday August 13th for the 6th video in the series.
Today’s Ask the Guru answers reader questions about sue of beams for an implement storage building, a question stumps the Guru so he asks readers for help, and if a post frame building could be built with a walk-out basement.
DEAR POLE BARN GURU: I want to build a Implement Storage 60’ x 24’ pole barn that has 10’ high sides and is open on in the front of the 60’ side. We would like to use 12’ spacing on the 6×6 posts. We were thinking of using 2×12’s for the beams on top for the trusses to bear on.. Can we just use all 12’ long beams or do we need to use 24’ beams to stagger the joints at the post? KERRY
DEAR KERRY: There are far more efficient ways than using beams between trusses. I would suggest – use glulaminated columns, they are going to be stronger, straighter, lighter and pressure preservative treated far better than 6×6 timbers. Place trusses directly aligned with sidewall columns (this will eliminate need for truss carriers – beams between columns). Use a single truss on each endwall, double trusses at interior columns. This method eliminates risky truss-to-beam-to-column connections and provides for a greater clear height when entering building on open sidewall.
DEAR POLE BARN GURU: 4″ wall thimble for micro boiler to fit flush against exterior siding as the rib would prevent this from happening. The ribbing runs vertical on my building. Do you have options/idea for a workaround for this? DAVE in VIROQUA
DEAR DAVE: You have me stumped. While I do not have your answer, I will post this up on “Ask the Pole Barn Guru” and see if some of our tens of thousands of readers have a good recommendation.
DEAR POLE BARN GURU: I have a sloped property and house with a walk out basement. I need a shop and the land drops naturally. Instead of using fill dirt I’ve considered a walk out basement with a pole barn. I’d like to be able to drive cars over the basement. Is that possible? TINA in IDAHO CITY
DEAR TINA: This is absolutely possible. Where you are excavating into your hillside, we can provide a Permanent Wood Foundation, incorporating columns for upper level into it. Your upper level floor can either have interior columns, beams and joists, or (and my preference) engineered floor trusses. Although on stilts, rather than cut in, this post frame garage has an elevated floor: https://www.hansenpolebuildings.com/2022/11/what-to-do-when-the-old-post-frame-garage-has-issues/

Post Frame and Glulaminated Columns
When it comes to using glulaminated columns in post frame buildings, most envision ones where lower portions (usually six to 10 feet) are pressure preservative treated and upper remain untreated. Most of these are products of highly graded Southern Pine and/or MSR (Machine Stress Rated) or MEL (Machine Evaluated Lumber).
For columns to be mounted into ICC-ESR Code conforming wet-set brackets there are other alternatives. Standard glulams for construction typically have a Fb (fiberstress in bending) of 2400 pounds per inch. This compares favorably to familiar pressure treated lower glulams, where most have a Fb rating of roughly 1900.
There are four basic appearance classifications for glulam beams as defined in APA-EWS Form No. EWSY110 and ANSI A 190.1 (although in ANSI A190.1 they are referred to as glulam appearance “grades”). Classifications are as follows: Framing, Industrial, Architectural and Premium. These classifications are summarized below and relate to a glulam beams’ appearance only, not to its strength.
Framing Appearance
This classification is provided to match standard dimensional lumber widths (typically 3-1/2” and 5-1/2” widths). Glulam members will be planed in a “Hit and Miss” fashion. Low laminations, glue smear and glueline squeezeout are permitted. Knot holes, splits and wane are also permitted and will not be filled.
Industrial Appearance
This classification should be used (specified) when appearance is not of primary concern. Loose knots and knot holes appearing on the wide face of laminations (beam bottom) exposed to view will be filled with putty, but voids appearing on lamination edges will not. Occasional misses, low laminations or wane are permitted.
Architectural Appearance
This is a high quality appearance suitable for applications where appearance is important but not an overriding consideration. All exposed knot holes and voids measuring over ¾” will be filled with a wood-tone filler. Exposed surfaces will be smooth and bottom corners (edges) will be eased.
Premium Appearance
This is the highest standard glulam appearance classification. All exposed knot holes and voids will be filled with a wood-tone filler. Exposed surfaces will be smooth and bottom corners will be eased.
For post frame columns above grade, framing or industrial appearance glulams will be most cost effective. Wanting to create some spectacular beamed ceilings or open trusses? If so, architectural or premium appearance might just be your ticket.
