2. What is Earthquake…?
• An earthquake (also known as
a quake, tremor or temblor) is the result of a
sudden release of energy in the Earth's crust
that creates seismic waves.
The seismicity, seismism or seismic
activity of an area refers to the frequency, type
and size of earthquakes experienced over a
period of time.

3. Sources of Earthquake
• Tectonic plates
• Volcanic eruption
• Nuclear explosion

4. Plate Tectonics

11. What is Earhquake Resistance
Building?
• Building designed to prevent total
collapse, preserve life, and minimize
damage in case of an earthquake or
tremor. Earthquakes exert lateral as well
as vertical forces, and a structure's
response to their random, often sudden
motions is a complex task that is just
beginning to be understood.

12. Techniques to resist Earthquake
• Active & Passive system
• Shear walls
• Bracing
• Dampers
• Rollers
• Isolation
• Light weight material
• Bands
• Others

13. Active System
Active control systems are devices
integrated with real-time processing
evaluators for improved service and
safety.

14. Passive System
Passive control systems are conventional
devices to resist or absorb the energy
produced during Earthquake.
For example: Viscous Dampers

16. Shear Walls
• Resist;
• Gravity Loads
• Lateral Loads

17. Shear Wall
• March 3, 1985 Earthquake (Chile) Shear
Wall performed very well

24. Liquid Tuned Mass Damper

25. Light weight material
• In recent times, many new systems and
devices using non-conventional civil
engineering materials have been
developed, either to reduce the
earthquake forces acting on a structure or
to absorb part of seismic energy.

35. Avoid Hammering & Pounding

36. Suggestions
• Avoid weak column and strong beam
design
• Provide thick slab which will help as a
rigid diaphragm
• Provide cross walls which will stiffen the
structures
• Provide shear walls in a symmetrical
fashion

37. • Increase in the transverse (Shear)
reinforcement.
• Horizontal lintel band should be provided
• Revision/ updation of building code of
Pakistan
• The building must be regular and
symmetrical in shape
• Reinforcing bars should be provided at
the corners and the junctions of the walls
