  1. Construction of Buildings to Prepare for Earthquakes What structures are needed to prevent serious damage ?

  2. Essential Structure Needed For Preparation Lateral Force Resisting Elements -Prepare buildings against wind and seismic forces Shear Walls Braced Frames Moment Resisting frames

  3. Shear Walls Made Of: • sheathed wood-frame walls • Reinforced masonry • Reinforced concrete

  4. Braced Frames • Concentric Frames -have diagonal braces allowing forces to act along one axis • Eccentric Frames -Both axis of braces to resist force

  5. Moment Resisting Frames • Made of steel, masonry and concrete • Beams and columns are bent for resistance of lateral forces • Two types -Special (more resistant to seismic forces) -Ordinary

  6. Prepare For Earthquake • Home Preparation • Checking for Home Hazards • Essentials for Survival

  7. Home Preparation • Emergency Plan -Safe Places under heavy tables, insides of hallways and corners of rooms -Dangerous Places near windows or mirrors, under heavy objects that may fall on you and doorways.

  8. Checking for Home Hazards • Electrical Hazards • Chemical Hazards • Fire Hazards

  9. Infrastructures Needed to Cope With Emergency • Smoke detectors • Fire extinguishers • Installing Security Lights • Extra Batteries • Flashlights • Radio • Life support systems should be prepared
