Japan, like Türkiye, is known as an earthquake country. The country, which survives a major earthquake almost every year without any damage, owes this to the precautions it took. We will examine E-Defense, one of these measures.
E-Defense, One of the world’s largest earthquake simulators. This defense system can lift even 10-storey buildings and test them as if they were being shaken by the world’s most frightening earthquakes.
The huge platform has shaken hundreds of structures so far. provided critical information for building earthquake-resistant structures.
It would be useful to watch this simulation first. (Starts at 0:27.)
Japan took a major step to counter such disasters after the 1955 Great Hanshin Earthquake.
The earthquake in Kobe was truly a turning point for Japan. 6.8 magnitude earthquake It caused great destruction in the city.
According to architect Alastair Townsend, as a result of this earthquake 150,000 properties became unusable, 300,000 people were left homeless and 6,300 people lost their lives. There were also fires after the earthquake.
The Japanese government began building earthquake simulations to prevent the disaster from recurring.
Following the disaster in Kobe, Japan’s National Institute of Earth Science and Disaster Prevention (NIED) Able to simulate magnitude 7 earthquakes began to develop a giant shake table.
This project, completed in 2005, Known as E-Defense and a true engineering marvel.
E-Defense, shaking multi-storey buildings in three dimensions Simulates earthquake effects. Experiments are monitored through cameras and sensors placed outside and inside the structures.
The shake table works using hydraulic systems.
Four huge gas engines in the building provide energy to hydraulic pumps. Like this Thanks to special joints and pistons, the platform It can move in three dimensions.
System, While pushing some structures to the point of collapse in others it demonstrates the effectiveness of structural reinforcements.
Also tested rooms; equipped with real furniture and even human figures It provides a more realistic simulation. The information obtained is used to ensure that future structures are more resilient to disasters.
E-Defense is considered a turning point in earthquake science.
from around the world engineers to test their structures in this unique facility brings.
Don’t you think it’s an engineering marvel that should be taken as an example? from within human “I wish we had it too.” He can’t help but think…
