Seismic Resistant Buildings

Building designed to resist the seismic waves is called Seismic Resistant Buildings.

Need for Seismic Resistant Buildings

• Control and Reduce the Extent of Damage.
• Durability (Increase durability of Building).
• Save Peoples Lives.

What is EARTHQUAKE?

        Shaking of ground due to sudden release of energy in the earth's crust.

Causes of Earthquake 

1. Tectonics plates Movement( 95%).
2. Other Disturbances( 5%)- Volcanic eruption, landslides, and explosions.

PRINCIPLES OF EARTHQUAKE RESISTANT BUILDING

Every building is expected to experience moderate to major earthquakes during its life period. The main principle of earthquake-resistant design is the building should not collapse whatever may be the damages either repairable or irreparable.

The collapse of RC buildings is generally preventable if the following principles of earthquake-resistant design are observed:-

❖ Failure should be ductile rather than brittle.

❖ Flexure failure should precede shear failure.

❖ Beams should fail before columns.

❖ Connections should be stronger than the members that fit into them.
