Earthquake Proof Buildings | Earthquake Resistant Buildings | Earthquake Resistant Structures




1.  An Appropriate Foundation: Creating a Flexible foundation for a building could help it stay standing during an earthquake. One opinion is to build the structure on top of pads that separate the building from the ground. Then, the pads move, but the building stays still. Another similar possibility described in the 2019 research paper, is to place a solid foundation slab made of reinforced concrete and crisscrossing strips atop an intermediate cushion of sand.

         This Approach also included a trench around the foundation for further protection. Since this foundation design kept the building's base away from the soil, it was more resistant to seismic forces.


2. Seismic Dampers: Earthquake-resistant buildings also need features to help absorb shocks. People more commonly refer to them as seismic dampers. Enginers worked with NASA to develop damper systems for swing arms on its rockets in the 1960s. It chooses a gas-driven shock isolation system first, then eventually progressed to a fluidics based system that's still used today during space station launches and for earthquake-proof buildings.


3. A Damage Mechanism: 

Polled water can create structural complications. That's why parking garages often have double tee-load bearing structures with a twist that lowers one corner- a feature called wrapping.

Structural Reinforcement: Enginers and designers have various methods for strengthing a building's structure against potential earthquakes. Many of those redirect seismic forces for example shear walls and braced frames transfer lateral forces from the floors and roof to the foundation.


4. Material with Adequate Ductility:

Ductility describes how well a material can tolerate plastic deformation it fails. Thus materials with high ductility can absorb large amounts of energy without breaking. Structural steel is one of the most ductile materials, while brick and concrete are low ductility materials.


5. Thoughtful decisions can save lives:

Tens of thousands of earthquakes happen globally every year. Even though some cause minor or no damage others lead to collapsed buildings, loss of life and tremendous disruptions to local economies.

Types of Plastering:- There are various kinds of mortars are accessible, for example, Lime Plaster Concrete Plaster Mud Plaster Stucco Plaster Lime Plaster:- The point when lime is utilized as a limiting material is called lime mortar. Lime mortar is a kind of mortar made out of hydrated lime, sand and water. Lime mortar is like lime mortar, the primary contrast depends on the use as opposed to the arrangement. Mortar for lime mortar is typically ready by blending sand and lime to equivalent extents, to further develop the strength little amount of concrete is added to it. Concrete Plaster mortar:- At the point when concrete is utilized as a limiting material, it is called concrete mortar. It is particularly appropriate for moist circumstances. Concrete mortar is typically applied in one coat. The thickness of the coat can be 12 - 15mm or 20mm relying on location conditions and the kind of building. 6mm thickness of putting of 1:3 or 1:4 Proportion is suggested for concrete putting of
