Earthquakes and Safe Construction Practices
The most successful way to minimize loss to life and property during earthquakes is to build disaster resistant buildings.
During an earthquake the ground shakes back and forth due to the plate movement under ground. The surface of the earth ruptures causing huge cracks; landslides occur; and sometimes tsunamis are generated during earthquakes. All these cause severe damage to building. Collapse of buildings lead to loss of life.
The Effects of Earthquake on Buildings
The vibrations of the earth during an earthquake make the building on the earthâ€™s surface to move. These vibrations cause the collapse of the building if the foundation is not strong enough.
Building collapse is the major cause for loss of life during an earthquake. So, to overcome this we have to build buildings that can withstand earthquakes.
Features for Earthquake Resistant Buildings
- Building should have a rectangular plan
- Reinforced concrete columns should support long walls
- Large buildings should be fragmented into small rectangular blocks
- The foundation of the building should be strong. Building constructors should ensure that there is no movement of underground soil once the building is built
- Doors and windows should be small and centrally located. This will ensure more stability to the walls
- Reinforces concrete bands are essential for all buildings. These bands have to be at the plinth level; floor level; lintel level; and roof level
- Vertical reinforcement should be provided at the corners and wall junctions
