Checking the strength of the walls and foundations of the shelter for the development of the reconstruction plan of the main building of the volyn regional children's clinical hospital

Abstract

Technical inspection is one of the main conditions in the development of a building reconstruction project. The detection of existing defects makes it possible to predict the so-called problem areas in the elements of the structures, which must be checked for the possibility of further operation and, if necessary, to provide measures to strengthen them. Conducting a technical inspection of the structures of the shelter of the main building of the Volyn Regional Children's Clinical Hospital in Lutsk was preceded by the need to check its strength structures for further recommendations regarding the reconstruction project.

The reconstruction plan envisages the addition of several floors to expand the institution's professional activities and increase the number of beds. The implementation of this project will, accordingly, lead to a significant increase in the load on the foundations of the building. Therefore, taking into account the proposals for the superstructure, it is first necessary to assess the current state of the load-bearing structures, check the strength of the walls and foundations for increased load, and provide recommendations on the operational properties of these elements.

As a result of a technical inspection of the structures of the shelter of the main building of the Volyn Regional Children's Clinical Hospital it was established that during the operation of the building, the structures received several defects and damage, but their condition can be considered satisfactory. In connection with the planned superstructure of several floors, the calculations of the walls and foundations of the shelter were performed based on the weight of the existing structures and the additional weight of the projected superstructure - 25 t/m.p.

By checking the strength of the load-bearing walls for the specified additional load from the designed upper floors of the building, it was established that the strength of the shelter walls is ensured with a tenfold margin. By checking the strength and reliability of the foundations, it was established that the margin of the strength of the foundation is 67%.
