Definition of earthquakes

PrincipleFocus of origin: Where a fault ruptures

Epicentre: Point above on the earth’s surface

The pulse of energy released by a fault movement radiates outwards as seismic waves, or

shock waves. Large, shallow earthquakes sometimes cause a surface rupture, as shown

above

Approaches in terms of using precast elements

Basic principles to start:

- Check on seismic intensity in the area

- Define the allowed damages to the building

- Focus on the design of the building:

structural simplicity

vertical constancy and regularity

bidirectional and torsional rigidity

stiffness and solid foundation

Description in dependence on FIB

Concepts of precast systems in seismic areas

Frame systems

Panel wall systems

Wall Frame systems

Floor framing systems

Double wall/ wall systems

Volumetric systems

Description in dependence on FIB

– Precast concrete building in seismic areas



Frame systems

- Describes the connection of beams and columns

- Used for open space buildings with high degree of flexibility

- For low seismic activity and low rise buildings

Typical Connections:

Frames with hinged beam to column connections

Frames with moment resisting connections

Column productionPrestressed beam production

Industrial building with beams

and columns

Hinged connection

Picture from: erico.com


Typical connection types:

Welding

Cast in - situ


Panel wall system

- Describes the connection of walls and floor/roof

- Used for low space buildings

- For low seismic activity and low rise buildings


Wall Frame systems

- Describes the connection of walls and frames

- Used if frame is not giving the needed strenght

- Wall used as shear wall

Picture from: erico.com

Grout in- and outlet


Typical connection types:

Cast in - situ frame


Floor framing system

- Floors used for transmission of horizontal forces into the resting

elements (walls, frames, ..)

- Typical used floors:

Filigree slabs, Hollow core, Double T, Solid slabs,…



Double wall/ wall system

- Used for low and high rise buildings of each type

Case study BauMax (Chile)

- Proof of connections – PDF

- Erection test 2 floor building - Video
