    • Sources ofEarthquake• Tectonic plates• Volcanic eruption• Nuclear explosion3Source: www.ecogeodb.com
    • Losses4
    • Techniques to resist Earthquake• Active & Passive system• Shear walls• Bracing• Dampers• Rollers• Isolation• Light weight material• Bands• Others5
    • 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
    • Inertial Forces7
    • Shear WallsResist;• Gravity Loads• Lateral Loads8
    • Shear Wall9March 3, 1985 Earthquake (Chile) Shear Wall performed very well

    • Seismic Zone24
    • HaunchesIn case of Joint failure,• Use High strengthconcrete• Increase section nearjoints• Provide haunches.25
    • 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
    • Suggestions27Source: www.eec.edu.pk
    • Suggestions28Source: www.eec.edu.pk
    • Avoid Hammering & Pounding29
    • 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
