facsimile of his patent for reinforced concrete as a substitute for timber

1855

“My invention has a new product as its object, which serves to replace the timber in shipbuilding and wherever it is at risk of damage through moisture, like in wooden floors, water tanks, plant pots, etc…..Ferciment.”

several advantages of concrete

•  cheapness

•  simplicity

•  rapidity in execution

•  fire resistance

Reinforced concrete #the materials #

•  cement –  Portland cement –  lime, iron, silica and alumina

•  sand and aggregate •  water

•  concrete mix •  reinforcement

Hennebique and the Hennebique system

where you have bending

where you have tension

continuous beam

•  rigid connection continuous beam/column

Structural Materials: Reinforced Concrete

Material Properties

•  High strength in Compression (concrete)

•  Relatively high strength in tension (reinforcing steel)

•  High density

•  Available in semi-liquid form (formable on site)

–  other materials can be combined into it

–  can be cast into wide variety of shapes

–  casting allows very effective rigid connections

Reinforced concrete #the workmanship #

•  steel fixing

•  formwork and false work

•  concrete mixing and placement

•  formwork

•  formwork –  wood –  steel –  plastic –  membrane (pneumatic

forms)

Concrete failures

Theories#concrete should be used as:

•  Flat masses unadorned with other material –  monolithic

•  Masses covered with ornament –  monolithic and ornamented

•  Original Forms –  by its own nature a frame--trabeated

Designing with concrete: issues

Where it’s cast: •  cast on site •  pre-cast (pre-fabricated)

How it’s strengthened: •  reinforced •  pre-stressed •  post-tensioned

Type of connections: •  continuous •  discontinuous
