Earthquake Resistant Building and Disaster Management
II nd Year Civil Engineering.
Ck College Of Engineering & Technology JayaramNagar, Chellangkuppam, Cuddalore 607003.
Earthquake occurs when to tectonic plates move suddenly against each other.
Earthquake is also known as temblors.
Waves spread from the epicenter, the point on the surface above the hypo centre.
During earthquake rock suddenly shift from their position and fracture occur on the earth surface.
Ground shaking from earthquake can collapse buildings, bridges, phone services etc.,
TECHNIQUES TO RESIST EARTHQUAKE
Active and passive system
Light weight material
Introduce flexibility to the structure.
Building is rested on flexible pads (base isolators)
When earthquake strikes the building does not moves
It is suitable for hard soil only
In India base isolation technique was first demonstrated after 1993 killari earthquake.
TYPES OF SEISMIC DAMPERS
Viscous dampers (energy is absorbed by silicone-based fluid passing between piston cylinder arrangement).
Friction dampers (energy is absorbed by surfaces with friction between them rubbing against each other).
Yielding dampers (energy is absorbed by metallic components that yield).
Viscoelastic dampers (energy is absorbed by utilizing the controlled shearing of solids).
Immediate steps must be taken to preserve our environment for our future generation.
Vertically oriented wide beams
It carries seismic loads down to the bottom of foundation
Provides large strength and stiffness to buildings.
Thickness generally varies from
150mm to 400mm in high rise buildings.
AVOID SOFT STOREY- CONTINUE WALLS IN GROUND STOREY
LIGHT WEIGHT MATERIAL
The group called paksbab is to find the solution for all problems.
It is to protect and improve the lives of the poor, especially in seismic and temperature region.
It is simple load bearing design.
Made with locally fabricated compression moles and manually operated form jacks.
Strong column, weak beam
Horizontal band necessary through the masonry(a building with no horizontal linet band collapse of roof and walls).
Latur earthquake incident(a building with horizontal linet band in killari village: no damage).
KEEPING BUILDING UP-RIGHT
When the quakes strikes the system dissipates energy in the building cores and exteriors.
The frames are free to rock up and down within fittings fixed at their bases.
Recently discovered technique of japan
It has found to be survived even in extreme earthquakes.
Regular testing of construction material at qualified laboratories.
For example, testing of bricks.
Period training of workmen at proffosional training house.
Onsite evaluation of the technical work.
