Introduction to Post-Frame Building Systems

• Identify the versatility and range of applications for

post-frame building systems

• Identify the structural features that make post-

frame building systems unique

• Introduce the basic design methods for structural

design of post-frame building systems

• Identify the available resources for design of post-

frame building systems

• Identify key performance characteristics of post-

frame building systems

Learning Objectives

POST-FRAME BUILDINGS: A LIGHT-COMMERCIAL MAINSTAY

“With so many structural framing options, building functions, and architectural finishes, post-frame building systems are limited only by the architect’s imagination and creativity.”

“Post-frame contributes very well to both the environment and the value for your dollar.” —Cheryl Ciecko, ALA AIA LEED AP CSI GGP, technical director,

WoodWorks, a nonprofit initiative of the Wood Products Council

• Versatility and range of

applications

• Structural features that

make these systems unique

• Key performance characteristics
• Resources for designing post-frame building

systems

LEARNING OBJECTIVES

Many architects, design professionals, code

• fficials and insurance companies are unfamiliar

with post-frame

• It is not commonly included in traditional

architectural school curricula

• They incorrectly equate post-frame construction

with post-and-beam construction

• They think post-frame is only for agricultural

buildings (i.e., barns, storage facilities, or horse facilities)

WHAT IS POST-FRAME?

POST-FRAME IS EVERYWHERE

PRIMARY FEATURES OF POST-FRAME

Engineered concrete footings Concrete sized to meet wind loads Treated column anchors to resist wind uplift Splash plank Frost wall and footing with any required reinforcement Splash plank Columns sized to meet wind loads Steel anchor designed to resist wind loads Treated sill plate Splash plank Columns sized to meet wind loads Steel anchor designed to resist wind loads Treated sill plate Thickened edge Monolithic concrete slab

KEY FEATURES OF POST-FRAME

Eave Height Post Height Clear Span

Cross section

Post Footing Post Foundation Sidewall Post Truss Purlins Girts

Splashboard

• Wood sidewall columns
• Wide bay spacing - 8 ft. and greater
• Large clear spans - up to 100 ft.
• Embedded wood columns or concrete piers
• Attached wall and roof sheathing or cladding

form structural shearwall/structural diaphragm system for resisting lateral loads

KEY FEATURES OF POST-FRAME

• Solid-sawn, glued-laminated, or mechanically

(nail) laminated wood

• Nominal 6x6, 6x8, 8x8 or 8x10 cross section
• Typically spaced 4, 6, 8, 12 or 16 ft. on center

along sidewall

• Any portion of the wood post embedded directly

into the ground and 6 -12 in. above grade is pressure preservative treated to AWPA- recommended levels for ground contact

WOOD SIDEWALL COLUMNS

Spliced glued-laminated column

• 3-ply or 4-ply,

fabricated with 2x lumber

• Lower portion is

preservative treated

• Upper portion is

untreated

WOOD SIDEWALL COLUMN

WOOD SIDEWALL COLUMNS

Nail-laminated posts with treated bottom spliced to untreated top Preservative- treated splash board

WOOD SIDEWALL COLUMNS

Untreated Post Concrete Pier

PRESSURE PRESERVATIVE TREATMENTS

• Posts embedded in

the ground, specify:

• Use category UC4B
• r better per AWPA-

U1-09

• e.g., CCA@0.60 pcf

POST FOUNDATION OPTIONS: EMBEDDED TREATED COLUMNS

Treatment stamp

PRECAST OR CAST-IN-PLACE REINFORCED CONCRETE PIER

• Pre-cast reinforced concrete

pier with post attached above grade

• Entire assembly

pre-engineered

• Assembly usually fabricated

in factory and shipped to site as a single unit

PRE-CAST REINFORCED CONCRETE PIER

Reinforcement Cleat

CAST-IN-PLACE CONCRETE FOUNDATION WALL

Untreated Post Connection Hardware Cast-in-Place Concrete Foundation Wall

THICKENED CONCRETE SLAB

THICKENED CONCRETE SLAB

• Blow-molded plastic or HDPE

plastic protective barriers

• Provide moisture and insect

protection

• “Enhance protection of copper-

based chemical treated wood posts or laminated columns”

PROTECTIVE POST COVERS

• Pre-engineered metal plate connected 2x

lumber trusses typically spaced 4 - 8 ft. on center

• Heavier timber trusses for larger post and truss

spacings and aesthetic requirements

• Solid-sawn wood rafters spaced 2 - 4 ft.
• n center for shorter clear spans
• Glulam rafters for larger rafter spacings or clear

spans

ROOF FRAMING

ROOF FRAMING

Trusses Sidewall Column (connected to trusses)

• Posts are connected directly to the roof framing

if post and roof framing spacing are the same

• Posts and roof framing are often connected to

header beams if post and roof framing spacing are not the same

POST TO ROOF FRAMING CONNECTIONS

POST TO ROOF FRAMING CONNECTION

Block Height Block Connection is usually a pinned connection (not a moment-resisting connection)

POST TO ROOF FRAMING CONNECTION

POST TO ROOF FRAMING CONNECTION

SOLID SAWN POSTS

1½” Connection with truss fastened to slide of post and with bear block Connection with truss bearing on notch in post Typical post-to-truss connection details for a solid sawn post application

ROOF PURLIN PLACEMENT

Purlins oriented flat

• r “on edge,”

depending on truss and purlin spacing Purlins placed either

• n top or inset

between truss top chords or inset between roof rafters

ROOF FRAMING AND PURLINS

Truss Purlin 2 ft o.c. Connection to Post Connection 8 ft o.c.

• Typically 2x4 to 2x8 solid sawn lumber, spaced

24 - 32 inches apart

• Oriented “flat” on outside face of wall post for

smaller post and girt spacings and loads

• “On edge” between adjacent posts for larger

loads or post or girt spacings

WALL GIRTS

Wall Girt Sheating

WALL GIRTS AND SHEATHING

SECONDARY FRAMING AND BRACING

• Corner bracing in upper chords of trusses
• Diagonal bracing for lower chords of trusses
• Lower chord stiffeners for trusses
• Cross-bracing of selected compression webs
• Continuous longitudinal bracing of long

compression webs and chords of trusses

• ANSI/ASAE (ASABE) EP 484 for diaphragm
