  4. 4. Losses4
  5. 5. Techniques to resist Earthquake• Active & Passive system• Shear walls• Bracing• Dampers• Rollers• Isolation• Light weight material• Bands• Others5
  6. 6. Active SystemActive control systems are devices integrated with real-timeprocessing evaluators for improved service and safety.6Passive control systems are conventional devices to resist orabsorb the energy produced during Earthquake.For example: Viscous Dampers

  25. 25. HaunchesIn case of Joint failure,• Use High strengthconcrete• Increase section nearjoints• Provide haunches.25
  26. 26. Light weight materialIn recent times, many new systems anddevices using non-conventional civilengineering materials have beendeveloped, either to reduce theearthquake forces acting on a structureor to absorb part of seismic energy.26

  29. 29. Avoid Hammering & Pounding29
  30. 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 thejunctions of the walls 30
