Abstract

The article aims to develop an instrumental model for a complex assessment of building structures that are subject to changes during their life-cycle process. This model can be used to substantiate the need either to reconstruct the existing building structures with the purpose of creating favorable living conditions or to demolish the building. The research methodology involved the general theory of systems and available techniques for estimating the state of building structures. Brick walls were tested by a nondestructive method using an IPS-MG-4.03 meter. Gypsum block masonry walls were tested by an ONIKS- 2.5 meter. Concrete was tested by an OMSh-1 hardness tester. Bellman dynamic programming was used to optimize the calculations and to find a solution for optimizing reconstruction costs. An example of assessing the condition of a building construction is provided, along with measures for extending its lifecycle. A conclusion is made that evaluation of the reliable operation of a building structure should consider the integral condition of the basic load-bearing structures under the action of environmental factors. This allows the risks of building destruction and the costs of building reconstruction to be reduced. For evaluating the current condition of the building under study, its structure was divided into a number of elements: foundation, wall box, floor slabs, roof. The hydrogeological parameters of the soil were also considered. Basing on the wear of building elements, the weakening coefficients of the building were calculated. The transient states of the system were described by semi-Markov processes. The results obtained can be used when evaluating the building residual life, selecting measures for improving the durability of structures with high wear and tear, and justifying the renovation concepts of territories.
