While old buildings remain standing intact, new buildings are often demolished. For example, consider Hagia Sophia, built in the 530s. How has it survived all these years? We asked the civil engineer…
Especially today, unfortunately, we constantly hear news of destruction due to earthquakes. These destructions both spiritual and material It’s happening.
Have you ever thought, Why do old buildings always survive? Are new buildings being demolished? We got the answer to this question from the civil engineer.
“The materials and construction techniques used in old buildings are superior to today’s conditions due to certain features.”
According to the civil engineer; Even though today’s technology is much more advanced, economic and financial expectations In addition, due to material supply and increasing labor costs, structures are built with expectations in many aspects other than safety and longevity, so it is natural to observe a decline in these issues compared to the past.
He explains the effect of the ingredients as follows:
“Since there were not many alternatives and lightened equivalents of the old materials, structures were built with solid rock and stone materials obtained from nature and their derivatives. The lifespan of a stone in nature also determined the lifespan of the material. It is obvious that natural materials are superior to composite materials created in laboratory environments today in terms of durability and adaptability to multiple environmental conditions. This superiority makes the structures superior when used as the basic material of the buildings.”
He also touches upon construction techniques:
Load distribution is carried out on solid materials with the arched-vaulted structure logic, which was generally determined in old buildings and is still valid today. geometric benefits It was done by eye. “When this load distribution was done geometrically well in materials with high bearing strength, the margin of error was reduced to lower levels because the principles of working together were taken into consideration rather than the bond between them.”
“Instead, today, the ability to make concrete and iron work together, such as reinforced concrete, and to manufacture without losing their load-carrying capacity while working, cannot be fully achieved. If it is provided, no design is made to achieve a safety coefficient above the safety coefficient in the old structure. Generally It will not collapse due to earthquake damage for 30 to 40 years It is designed this way.”
The reason for this is both economy and the conscious obsolescence that raw materials offer us.
According to our engineer everything has financial value In today’s world, it is a priority for the building to fulfill its function and to consume a minimum of money and time.
In the past, the mentality was to leave a permanent legacy other than money and for states to show themselves. building structures with solid history because he wants to. For example, Hagia Sophia; He concludes his words by saying that it is an unforgettable building that we are still curious about in terms of its 21st century materials, techniques and duration, and which is visited by thousands of people every day.
