The problem is solved through the mathematical simulation of the stress-strain state of the examined construction and during the experimental investigation of the behavior of the structural elements. © 2019 The Authors.

However, at the stage of their construction there are many deviations from the design project that cause a variety of defects, including those of technogenic nature, which may lead to structural failure and consequently to human injuries/fatalities (Prokopov and Tkacheva, 2015). Urgent issues arising during the construction and sci-tech support of complex engineering structures (steel oil storage tanks in our case) involve the assessment and monitoring of the stress-strain state of these structures and the analysis of the behavior of load-bearing structural elements at all stages of their life (Mansurova et al. , 2014). A separate place in this paper is devoted to the peculiarities of using strain gauges in severe environment. The significant dynamic deformations that are realized in the steel oil storage tank during the experiment had a negative impact on the measurement quality. An important feature of the experiment was the experience of measuring deformations in an aggressive environment and sharp temperature t i , t l l ti t t t i t t ti l t l il t it t t t t li t t i i l i t l t. l i l t t t ti l i l ti t t t i t t t i t ti i t i t l i ti ti t i t t t l l t . thors.
