  1. 1. Welcome <br />
  2. 2. EARTH QUAKE ENGINEERING<br />DEFINITION:<br />As a branch of engineering devote to mitigating earthquake hazards.<br /> earthquake engineering covers the investigation and solution of the sproblems,created by damaging earthquakes.<br /> In planning ,designing ,constructing and managing earthquake-resistant structures and facilities<br />
  3. 3. EARTHQUAKE<br />Is the result of a sudden release of energy in the earth’s crust that creates seismic waves.<br />That’s makes the ground shake<br />After a while ,the rocks are break ,the earthquake occurs.<br />
  4. 4. EARTHQUAKE EFFECTS -1<br />
  5. 5. Effects-2<br />
  6. 6. EARTHQUAKE LEVELS<br />CONTENTS:<br />Zone-1<br />Zone-2<br />Zone-3<br />Zone-4<br />Zone-5<br />
  7. 7. ZONES<br />ZONE-5:<br />The highest risks zone that suffers earthquake.<br />The IS code assign zone factor of 0.36 (36% of gravity)for zone-5.<br />It is reffered to as the very high damage risk zone. Himalayas, Punjab, Kashmir fall in this zone.<br />
  8. 8. ZONE-5 EFFECTS<br />
  9. 9. ZONE-4:<br />The IS code assigns zone factor of 0.24 for zone- 4.<br />Country-Delhi ,Jammu ,Bihar fall in zone-4.<br />
  10. 10. ZONE-4 EFFECTS<br />
  11. 11. PROBLEMS<br />Construction materials are not quality.<br />In this generation the buildings are taken the time at maximum 5years and to fall on the ground.<br />Because as the engineer was did the carless mistake to construct the building.<br />Do not check the building.<br />
  12. 12. SOLUTIONS<br />Introductory remarks.<br />Importance of construction & maintenance.<br />Need for a comprehensive approach to Earthquake-resistant construction.<br />Importance of conceptual design.<br />Control or decrease of demands.<br />
  13. 13. INTRODUCTORY REMARKS<br />Numerical design of structures ,particularly in establishing the design earth-quake shaking and in estimating the demands and predicting the supplies of the real three-dimensional soil-foundation-building system.<br />Thus construction and maintenance, which includes repair, retrofitting and modification , must also be considered in addition to the design aspects.<br />
  14. 14. IMPORTANCE OF CONSTRUCTION & MAINTENANCE<br />Design and construction of a structure are intimately related and the achievement of good workmanship depends.<br />To a large degree , on the simplicity of detailing of the members and of their connections and supports.<br />
  15. 15. NEED FOR ACOMPREHENSIVE APPROACH TO EARTHQUAKE-RESISTANT CONSTRUCTON<br />To covered by existing seismic code procedures has been discussed by the author in several publicaton.<br />Behavior of the structure –serviceability , damageability , and safety against collapse.<br />Depending on the limit state controlling the design. <br />
  16. 16. IMPORTANCE OF CONCEPTUAL DESIGN<br />In any current seismic-resistant design procedure<br />It is necessary to pay more attention to conceptual design.<br />As the avoidance or minimization of problems created by the effects of seismic excitation by applying an understanding of the behavior rather than using numerical computations.<br />
  17. 17. CONTROL OR DECREASE OF DEMANDS<br />The foundation-superstructure system response ,the conceptual idea would be to control the input to the structure foundation.<br />A decrease in demands can be achieved by proper selection of the configuration of the building.<br />Followed by the basic principles or guideline for achieving efficient seismic-resistant construction. <br />
  18. 18. <ul><li>NATURE WILL HAVE HER COURSE</li></ul>- so don’t feel.<br />
  19. 19. NO GOOD WORK IS EVER LOST<br />- SO TRY AGAIN<br />
  20. 20. THANK YOU <br />AND AGAIN WELCOME<br />
