Model updating by deformation monitoring data

The mathematical model is important for deformation monitoring of buildings and structures. The model is used both at the system design stage and at the stage of operation. A mathematical model created on the basis of documentation and design drawings is sufficient for the design stage. This model may not be suitable at the stage of operation of the monitoring system due to various reasons. Changes in the structural properties may also occur during monitoring. This also requires model updating. In this paper, we propose a version of a deformation monitoring system, which includes “primary” and “verification” sensors. The data from the “primary” sensors are used in the model as input parameters, and the data from the others are used to verify and update the model. The verification of the adequacy of the model used in the deformation monitoring system must be provided by a correlation between the indications of different types of sensors. The paper shows one of the adaptation variants of the model according to the data of the deformation monitoring system of a building located in a karst area.
