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

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

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

25. Haunches
In case of Joint failure,
• Use High strength
concrete
• Increase section near
joints
• Provide haunches.

26. 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.

29. Avoid Hammering & Pounding

30. 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
•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 30
