The aim of the work is to develop, through selection, adaptation, and improvement of resource-efficient engineering solutions and restoration technologies, the structural integrity of reinforced concrete and prestressed concrete load-bearing structures, as well as brick and profiled thin-sheet steel enclosure structures of buildings and facilities damaged by armed conflicts and terrorist acts.

The scientific novelty of the work lies in addressing urgent social and economic problems of the state associated with the major repairs or reconstruction of buildings and structures that have been damaged or destroyed as a result of emergencies, armed conflicts, and terrorist acts. As a result of the completion of the work, the following outcomes are expected:

first time:

  • A methodology for manufacturing pre-stressed non-separable reinforced concrete structures with reduced steel consumption has been developed and experimentally confirmed. These structures can be created both during new construction and during the strengthening of damaged reinforced concrete elements with steel profiles or damaged steel elements by concreting;
  • The possibility of using spiral silo enclosure structures with folded connections for the restoration of self-supporting steel enclosure structures of bulk material silos is envisaged;

improved:

  • Typical resource-efficient structural solutions of self-stressed reinforced concrete structures that have an increased level of durability under abnormal loads of a man-made nature;
  • The design of detachable joints for the restored (replaced) load-bearing prestressed concrete elements instead of damaged (destroyed or partially deformed) elements;
  • An engineering methodology for calculating the strength of complex-loaded deformed masonry subjected to combined vertical and horizontal loads based on the theory of plasticity;

received further development:

A methodology for considering the pre-stressed and deformed state of components in reinforced concrete structures.

Number of publications: one individual monograph, five collective monographs, including one in international publications (total creative contribution of the authors - 17.6 printed sheets); 17 articles in "Category A" journals (including 17 in international publications) and 17 articles in "Category B" journals. The total number of references to the authors' publications and the h-index for the work according to the databases are as follows: Web of Science - 0/0, Scopus - 54/8, Google Scholar - 52/11. Six utility model patents have been obtained in Ukraine.
