New technology in earthquake engineering to resist collapsing of the structures
It is the big challenge for the structural engineers to develop earthquake resistance structures.
An Earthquake resistant structure should have the capacity to resist abrupt ground shaking to reduce the damages to the structure.
Though the reinforced Concrete contains sound earthquake resistance capacity of buildings but owing to the substandard mix design of concrete and improper curing the reinforced concrete lost it’s desired compressive strength and it leads to collapsing of structure during an earthquakes.
Recently, a new innovation is launched in earthquake engineering where the curtain of cables is affixed to ground to significantly enhance the earthquake resistance strength of the building.
In these technology threads are used which are created with thermoplastic carbon fibre composite. These threads are fastened and knotted to produce a strong flexible rod which is 90% lighter as compared to reinforcement bars and contain the equivalent strength.
To resist earthquake successfully, these composite rods are fastened & secured from the roof to the ground and set up around the building. Rods are also set up inside the building to make the interior walls stronger.
These Composite threads are formed with textiles so that the rods can expand and pull the structure back in opposite direction to withstand shaking of the structure.
When an earthquake occurs, in case the building is pushed towards left side, the threads or rods located on right side pulls it back to retain the building in exact position and significantly reduces the structural damage and human death.
For online demonstration of this new technology, go through the following video tutorial.
