Converting a Traditional Framing Plan to Post-Frame

Converting a Traditional Framing Plan to Post-Frame

“Hello, I am looking to convert my traditional; framing plan to post-frame framing to get my walls up quicker. I would like to know what requirements need to be followed. The information I already have is that it’s best for the post to be 4ply 2×6 for anything higher than 10′. The girts are to be 24″ on center. I will also be using the post frame with concrete block basement walls. I will wet-set the column brackets. I just need to know what other factors need to be addressed to get the plan reapproved. thanks so much for your help!”

You are correct about post-frame’s speed for getting dried in. Post-frame is extremely material efficient, eliminating redundant members found in prescriptive stick framing. This makes for both quicker assembly and better insulated exterior walls.

Our post-frame engineers have provided code compliant structural designs for thousands of buildings in all 50 states. They will determine column sizes based upon your building’s dimensions (width, length, height and slope of roof) and climactic conditions at your specific site. You will find they will specify either solid sawn or true glu-laminated columns, rather than nailed up (or nails and construction adhesive joined) as an appropriate design solution for long-term best results.

In order to minimize construction steps, material usage and create a deep insulation cavity, expect to see a design using commercial bookshelf girts. These will be placed horizontally 24 inches on center between columns. (Please read more here: https://www.hansenpolebuildings.com/2011/09/commercial-girts-what-are-they/).

Bookshelf wall girts also provide an excellent design solution for obtaining optimum finishes on interior faces of exterior walls https://www.hansenpolebuildings.com/2019/09/11-reasons-post-frame-commercial-girted-walls-are-best-for-drywall/

We have provided a plethora of fully engineered post-frame homes utilizing ICC-ESR Code approved wet set brackets mounted to concrete, ICF and CMU (concrete block) walls and your engineer sealed plans will include design of these walls.

Post Frame Glulaminated Columns

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.
