The complication of element design performance of artificial structures leads to the need for more detailed superstructure modeling, since simplified models don`t always allow taking into account deformation features of elements. In addition, during the building period, the actual stress-strain state of structures can be significantly influenced by factors that are difficult or impossible to account for at the design stage. Correct modeling of deformation of elements is one of the essential conditions for the prevention of emergencies during construction, maintenance or timely elimination of the consequences of such incidents with minimal losses. When performing this kind of work, attention should be focused on the most significant design parameters, which comprehensively reflect the nature of the structure operation. This will make it possible to effectively carry out control and promptly make appropriate adjustments to the building process, if it is necessary. The article describes an example of the simplified model modernization to more fully match its actual deformation and the experience of eliminating the consequences of emergency that arose during erection of unique bridge. Thus, the importance of adapting the computational model to the actual nature of the engineering design is confirmed.
