On the 27th, three weeks have passed since the massive earthquake that struck southern Turkey on the 6th of this month.
On the night of the 27th, a debriefing session was held by the experts who conducted the survey on site, and it was said that it was more important than anything to thoroughly follow the latest standards for construction, as large-scale damage was conspicuous in buildings with old earthquake resistance standards and weak strength. pointed out.
On the night of the 27th, the "disaster prevention academic collaboration body" made up of organizations related to disaster prevention, such as the Architectural Institute of Japan and the Seismological Society of Japan, held a report meeting on the major earthquake that occurred in southern Turkey on the 6th of this month.
Among them, Assistant Professor Fati Sutu of Istanbul Technical University, who investigated buildings in Kahramanmaras and Adiyaman, which are close to the epicenter, reported on the state of the damage via a web conference system.
A large-scale collapse in which a building collapses almost vertically, called a pancake crash, is often seen in buildings built before 2000, when Turkey's earthquake resistance standards changed significantly, and these were simply not strong enough in design. However, he explained that there were construction problems, such as a small number of reinforcing bars in the concrete pillars.
On the other hand, there was no damage to hospitals with seismic isolation structures built according to the new standards, and there were cases where surgeries were able to continue even during severe shaking. He expressed the opinion that it would not have collapsed.
After the debriefing session, Assistant Professor Fatih Schu said, ``In this earthquake, the lesson was not to change the seismic resistance standards, but how to comply with the standards. I need it,' he said.
