precast concrete construction

precast concrete

also known as prefabricated

standardizing and mass producting from a plant outside of the project site

requires interaction between design and production planning

Joseph Monier

[history]

a gardener developed permanent planters at a low price and patented different products made of reinforced concrete

John Alxander Brodie

[history]

pioneered precast panelled buildings were pioneered in Liverpool, invented by this city engineer

his technology prompted the precast reinfoced concrete slab as means of building houses quickly and cheapl

Gosvenor Atterbury

[history]

used a similar technique as Brodie in the houses he built at Forest Hills Gardens

can be considered as a progenitor of the Modern Movement

National Precast Concrete Association

[history]

NPCA

specialized in the precast concrete products industry focusing on utility, underground and other non-prestressed products

Precast/Prestressed Concrete Institute

[history]

PCI

particularly dedicated to the precast concrete structures industry on prestressed concrete elements and on otehr precast concrete elements used in above-ground structures such as buildings, parking structures, and bridges

lattice girder

[history]

a main part of the so-called half precast system

was used for precast products which was the starting point for the industrial production of precast elements on a broad basis

large panel system

[categories of precast]

multi storey structures composed of large wall and floor concrete panels connected in the vertical and horizontal directions so that the wall panels enclose

they form a box like structure

when properly joined together, the horizontal elements act as diaphrams that transfer the lateral loads to the walls

cross wall system

[large panel system configurations]

the main walls that resist gravity and lateral loads are placed in the short direction of the building

longitudinal wall system

[large panel system configurations]

the walls resisting gravity and lateral loads are placed in the longitudinal direction

two-way system

[large panel system configurations]

the walls are placed in both idrections

frame system

[categories of precast]

can be constructed using linear elements or beam-column assemblages

preferred because of the dificulties associated with forming, handling, and erecting spatial elements

slab column systems

[categories of precast]

rely on shear walls to sustain lateral load effects, whereas the slab-column structure resists mainly gravity loads

lift-slab systems

[main systems of slab-column]

were introduced in the alst decade of the soviet union

consists of precast reinforced concrete columns and slabs that are assembled using special joints

lifted from the ground up to the final height by lifting cranes

prestressed slab-column system

[main systems of slab-column]

uses horizontal prestresisng in two orthogonal directions to achieve continuity

rc floor slabs fit the clear span between columns
