The aim of this work is the discovery of the peculiarities of the behavior of reinforced concrete monolithic frame building structures in fire conditions as a basis for evaluating their class of fire resistance by calculation. Object of research - the processes that occur under the influence of fire, the elements of monolithic frame structures. Subject of research - methods of estimating classes of fire resistance of elements of monolithic frame structures. The relevance of the work. Analysis of the death and injury of people and loss of property due to fire shows that one of the reasons a large number of fires associated with the restructuring of the public economy, restructuring of production and technological processes without regard to requirements of fire safety, and often their violation in the construction and reconstruction of objects. Given the high danger of fires today in the budget of all States allocate considerable resources to the prevention and elimination of fire hazard. Among the causes that increase social and economic losses during fires can be set on a substantial number of cases, when in buildings with monolithic-frame reinforced concrete structures do not comply with the requirements of normative documents on fire safety, in particular their resistance to fire. The situation is complicated by the considerable restrictions on the conduct of fire tests of such structures. There are known cases of fires, which had serious socio-economic consequences associated with the collapse of monolithic frame structures under the action of temperature effect of fire, it was a clear violation of the relevant statutory requirements. In the process, the following tasks were solved. Built design scheme of the exterior wall and the floor slab. Developed numerical algorithms for the implementation of the proposed calculation methods and test the results of calculations. Developed algorithms for calculations and obtained the corresponding results. On the basis of the results estimated class of fire resistance of external walls and floor slabs and installed in compliance with the requirements of normative documents. The results of the work are data on the fire resistance class of walls and slabs, as well as their compliance with the requirements of the building code to the studied structures.

Saving a scientific data set occurs in two stages:
1.) Creating a data set
Enter the name of the set, a brief description of the set (annotation), and click the “Create set” button. After that, a draft data set will be automatically created, which you can save for further work with the set. The system will redirect you to the “Data set information” page.
2.) Filling in the data
On the “Data set information” page, you need to fill in all the fields related to the data set and upload the files.
Please note! Each file is uploaded separately. This is done to ensure the stable operation of the system.
Once you have filled in the information about the scientific data set and added the necessary files, you can save the draft or send the data to the system.
Please note! Once the data has been sent, you cannot change it.
Drafts are necessary for storing the data set and editing it before sending.
All accounts on the NRA website go through a standard registration procedure and are verified. However, in order to obtain additional features, such as publishing open reviews of academic texts, verification by affiliation is required.
To obtain the status “verified”, you must change your primary email address to a corporate one, which is tied to a scientific or educational institution.
For example: user@ukrintei.ua, user@nas.gov.ua
After confirming your corporate email address, your account will be automatically verified by affiliation.
If your email address is corporate, but your account does not have a verification mark, you need to write to us at the email address NRAT@ukrintei.ua. After verification, we will add your address to the database, and your account will be verified.
After completing the verification procedure for affiliation, you can change the primary email address to a convenient one for you, without losing your status during the current verification.
You only need to verify for affiliation once.
* We use corporate addresses from the Unified State Database on Education and the State Register of Scientific Institutions Supported by the State
To search for news published on the official website of NRАT in the “News” section, you need to enter one word, several words, or an exact phrase in the search field. Different terms are separated by spaces.
The search is performed everywhere – in the title and the news text.
For a more comprehensive result, it is recommended to use word stems (parts of words without endings).
When using multiple words for the search, they are combined using one of the logical methods described below.
By default, the logical connector “and” is used. In this case, search results will include all news releases that contain the specified words, even if they are located separately from each other and are in different parts of the text.
Example: Search phrase: OECD report. Search result: all news containing the words “report” and “OECD” in the text and in the title, both together and separately.
If a phrase or phrase is enclosed in quotation marks (“), the results will include all publications where this exact phrase or phrase is found.
Example: Search phrase: “OECD report.” Search result: all news containing the exact phrase “OECD report.”
If you know the publication date of the news or are interested in a specific time frame in which they were published on the website, you can select such a date or date range in the additional field that looks like a calendar. The date is entered in the format year-month-day and confirmed by clicking on the corresponding date in the calendar dropdown. You can enter a date or choose one by browsing through the calendar by months and years. By default, the interval starts from the oldest date (2018-01-23) and ends with the current date.
You can also use one or more hashtags, which are located under the search field on the right side of the “News” page.
Please note: The search for academic texts is carried out in a separate search window at the following link https://nrat.ukrintei.ua/searchdb.
