When Regulations 1 is not enough for worn -out textures/The necessity of saving life from an silent earthquake catastrophe

According to RCO News Agency, While new edits of the Code are published with the aim of reinforcing earthquakes, one important point should not be forgotten, and it is only written for buildings that are to be built from now on and pay attention to the quality of existing buildings, while Iran’s urban reality is something else; Thousands of worn -out and non -man’s homes breathe in the old textures of cities, without relying on a standard.

Earthquake in Iran is not rare; From Bam to Kermanshah, we have gone through bitter experiences. But in the heart of many cities in the country, they live in neighborhoods that have been built on disregard for years; The worn -out textures whose homes were built many years ago without engineering supervision, regardless of the danger of earthquake and without awareness of technical regulations.

In these circumstances, the by -law, as the most important technical document of earthquake -resistant reinforcement, is not only an engineering requirement but also a necessity for survival. The Code says that the building must be able to tolerate earthquakes, save human lives, and remain shelter after the earthquake. Statistics show that much of the deaths of earthquakes in the country is related to old, unstable and non -structural buildings; The same ones that are hidden in the heart of worn -out tissues. When the earthquake comes, there is no opportunity to escape, nor a warning time.

Implementation of bylaws in worn -out textures means giving people the right to safe life for years who have been a victim of forgetfulness in urban development. That is, if the government, the municipality and the inhabitants work together, the great catastrophes can be prevented. But there are also challenges; From the high cost of renovation to public ignorance and complexity of ownership. It is here that the role of the media, education and supportive policies are important. Renovation of worn -out texture is not just the work of engineers; It is a national project to save the lives of citizens. It may be time for the Code of Conduct to come out of the office of engineers and see in the tight alleys of worn -out textures.

What does the bylaws say

Code 2 “Design of Buildings against earthquakes” was prepared by the Road, Housing and Urban Development Research Center and aims to increase the safety of buildings against earthquake risk in different parts of Iran. The Code has been drafted since year 5 and has been reviewed several times and the fifth version is the latest release. Newer versions have made significant changes in loading, material resistance, soil type and structural behavior.

The most important points of the Code of Conduct are the determination of earthquake -prone areas in Iran, in which the country is divided into four areas from low -risk to high -risk, and for each region, the expected earthquake intensity is specified.

Another highlight of the soil type of building is another point in this Code, which emphasizes the type and gender of the soil that has a great impact on how the building responds to the earthquake. In the Code, the soil is divided into different categories from hard to soft and the design criteria are proposed to it.

Architectural and structural design is another point in the by -laws that the building must be designed so that it does not fall under the effects of the earthquake. Side bearing systems are other topics in which a variety of earthquake resistance systems such as bending frames, shear walls, and brackets are identified and the application of each is determined by the type of structure and earthquake area.

“Reducing human casualties and financial losses in earthquakes”, “improving the quality of construction” and “prerequisite for construction finish” are among the approaches of the Code.

Problems that the bylaws are unable to solve

Dr. Ali Beitollahi, Head of Earthquake Research Center, Road, Housing and Urban Development Research Center In a conversation with ISNA Referring to the editing of construction bylaws in response to the question of what problems these edits are solved by the quality of construction, it noted: The bylaws compiled in this area are the construction of the earthquake construction by which these bylaws are for the part of buildings to be built.

He added: “The Code 2 has not been formulated for existing buildings and it is only for buildings that want to be designed and built, while our most important problem in this area is existing buildings.”

Beitollahi said: “From the 1980s and 1980s, when we started researching in this field, we found our worn out of the past and the question arises whether a neighborhood with worn -out texture can be transformed into a resilient neighborhood?” The answer is negative, because this is a very difficult task.

The head of the earthquake department of the Road, Housing and Urban Development Research Center, referring to the difficulties of converting worn -out tissues into resilient areas, explained: Some residents of these areas are tenants and some are masters and there is no collective agreement to renovate these tissues. Participation in the renovation of these areas should also be to construct several micro -construction plates and build an earthquake -resistant building unit.

“Another reason is the lack of confidence in government agencies; That is, residents of the areas with worn -out textures do not have the confidence and confidence that if they are excluded from their buildings for the purpose of rebuilding, they will be delivered in due time.

Beitollahi said that the roads of the worn -out tissue have under grain and impermeable texture. Therefore, there are problems in this area that drag the modernization and renovation in the worn -out tissues, and therefore the risk of earthquakes increases due to population growth.

“We expect that in the day -to -day reinforcement of appropriate materials and designs will reduce the casualties, but on the other hand, in the metropolis, unfortunately, due to the problems of changing the face of worn -out textures, it is very slow and negligible,” he said. So we need to be much more radical in this regard.

The head of the earthquake department of Roads, Housing and Urban Development, investment, incentives and public confidence is one of the country’s most important priorities in reducing seismic risk, and noted: The global document was signed by many countries to reduce earthquake risks and Iran is one of these countries. The document states that “investing in reducing risk is not a waste of money, but a kind of savings and investment for the future.”

Beitollahi emphasized: Today, we may devote credits to reduce earthquake risk to build better buildings in worn -out textures, but on the other hand we reduced the earthquake risk that is a kind of investment for the future.
