Study on project of earthquake resisting structure. Base isolation is measured.

2. Conventional Approach
• STRENGTH
• STIFFNESS
• INELASTIC DEFORMATION CAPACITY
• CAREFULL DETAILING-BEAM & COLUMN
CONNECTION

3. ADVANCE TECHNIQUES
• REDUCE E-FORCE
• NOT TO STRENTHEN
• TWO TECHNIQUES
– BASE ISOLATION
– ENERGY DISSIPATION DEVICE

4. BASE ISOLATION
• SUPPORT- SERIES OF BEARING PADS(BASE
BEARING)
– STIFF AND STRONG IN VERTICAL DIRECTION BUT
FLEXIBLE IN HORIZONTAL DIRECTION
– BUILDING UNDERGOES DISPLACEMENT
HORIZONTAL i.e. DEFORMATION

7. Mechanism
• Decoupling of super-structure from its sub-
structure resting on shaking ground.
• Due to horizontal motion, structure become
intact.

8. Earthquake EngineeringExamples
• Tomb of Cyrus (oldest base
isolated structure).

9. •La City Hall (Tallest).

10. National Museum
of Western Art ,
Tokyo.
•Safe guard essential equipment statues and
other works of art.

11. Earthquake Model
• Comprises of three steps:
– Earthquake generation table
– Base Isolation technique (Foundation)
– Super Structure
