Guide: Precast Concrete Structures (based on Kim Elliott)
Eurocode 2 (EN 1992-1-1)
A note of caution for younger engineers: The first edition of Elliott’s book relied heavily on British Standard BS 8110. However, later editions (particularly the 2nd and 3rd) have been updated to align with and EN 1992-1-2 for fire resistance.
- Shear wall (cantilever) systems: Rigid connections.
- Moment-resisting frames: Very rare in precast due to joint complexity; Elliott explains why a "ductile connection" is an oxymoron unless designed carefully.
- Braced frames using struts and ties.
- Tied connections: Corbel and pin.
- Bolted connections: Embed plates with Nelson studs.
- Cast-in sockets and loop-boxes.
The use of precast concrete structures has a rich history dating back to the early 20th century. The concept of precasting concrete involves casting concrete elements in a factory or on-site casting yard, allowing for faster construction, improved quality, and reduced on-site labor costs. One of the pioneers in promoting precast concrete structures was Kim Elliott, a renowned engineer and researcher who has written extensively on the subject, including his book "Precast Concrete Structures" (available in PDF format).
