Earthquake resistant designsDesign - but it is analysis of forces - buildings

due to loads acting on it.

If a building is enough to resist the earthquake, then such building is called Earthquake resistant structure.

Such design is called Earthquake resistant designs

Earthquake Resisting Structures Techniques:

BASE ISOLATION METHOD

ENERGY DISSIPATION DEVICE -(Seismic Dampers)

KEEPING BUILDING UP THRUST

Introduction of Resistant techniques

Thought - Base Isolation Devices - separate building from ground by some rubber devices.

Seismic dampers - special devices - introduced in building - absorb the energy - produced by seismic waves.

Base Isolation Method

5

It uses bearing pads that have a curved surface and low-friction materials similar to teflon.

During an earthquake the building is free to slide both horizontally and vertically.

It will return to its original position after the ground shakeing stops.

Seismic Dampers

7

Dampers are of:

Viscous Damper Friction Damper Yielding Damper

10

Keeping Building Up thrustWhen the quake

strikes the system dissipates energy in the building cores and exteriors.

The frames are free to rock up and down within fittings fixed at their bases.
