Pre-industrial wood buildings used

Log or frame construction

was mass-produced for single family houses post war

Stud frame construction

The post-war period

mass-produced flat-packed houses

An early example of a stud frame building is

Augustine Taylor St Mary’s Church

Augustine Taylor St Mary’s Church is located

in Chicago

An early example of solid wood construction is

Butler Square

Butler Square was built in

1908

Butler Square

a timber post-and-beam construction that was used to meet the warehouse’s heavy loading.

Large Solid Sawn timbers

Have been growing for a long time

Glulam

Parallel bonded dimensional lumber

In the last 20 years, what has re-emerged as a hi-tech material

Engineered lumber

Engineered lumber is also known as

Solid wood or mass timber

The wood innovation and design centre (WIDC) is by

Michael Greene architects.

The wood innovation and design center (WIDC) has

1. Glulam Columns and Beams

2. CLT floor slabs

3. CLT walls- Lift/services core

4. Integrated services

5. floor build up

Curved glulam

The Haesley nine bridges golf club house on Jeju island south Korea

Shigeru Ban made

Curved Glulam

LVL

Laminated veneer lumber

LSL

Laminated strand Lumber

PSL

Parallel Strand lumber

CLT

cross-laminated timber

Illwerke center Montafon is by

Hermann Kaufmann

What are the two hybrid systems

Illwerke centre montafon and The wood innovation and design centre

Illwerke centre montafon is

1. 120 meters long

2. 5 storey - hybrid system

3. Glulam columns and beams

4. concrete floors.

mass timber provides structural stability by

bonding together dimensional lumber

Bonding wood makes it possible to

predict its strength

By bonding wood it makes

it dimensionally accurate

Generally the visible “plys“

follow the direction of forces.

mass timber unique quality is that

it provides insulation through a burnt “Charred Surface”

Mass timber must be protected from

direct sunlight/UV light

Mass timber must not be exposed to

Rain, Standing water or allowed to soak.

Mass timber transmits

sound

Mass timber needs acoustic isolation to

Migrate sound

Mass timber stores

Carbon

How do mass timber store carbon?

Trees sequester carbon during their life pulling carbon dioxide from the atmosphere and storing it in their mass, roots, and surrounding soil until the three burns or decomposes or the soil is disturbed then the carbon is re-released into the atmosphere.

1 ton of carbon is contained in

1 cubic meter (35 cubic feet) of wood.

1 Metric ton of carbon is a sphere approximately

30 ft in height

Fire regulations meant

Oversizing the timber to meet 60 min fire rating.

site assembly

high levels of logistics

The advantage of Glulam is that

it exceeds the lengths of trees through lamination.

Glulams average height is

60’ tall

Swiss media center is by

Shigeru Ban

The Shigeru Ban building features

an interlocking post and beam structure with no metal fasteners.

The gravity loads in the Shigeru ban are carried through

a timber structure

What was the aim of the Shigeru Ban

To create warm interiors and visual juxtaposition of wood in the city

Hardwood beech plates reinforce the connection between

Column and beam

Operable windows allow

Exposure to fresh air

Wood to wood connections replaced by

Metal, Adhesive or all three
