On the Method of Solving the Problem of Generalized Rigidity Characteristics Identifying of Extended Load-Bearing Structures Using an Elastic Checking Unit

A method for identifying the generalized rigidity parameters of a load-bearing structure is proposed. This method is based on the formation of a general equation for the rigidity parameters using the least-squares method and the general equilibrium equation of an elastic checking unit represented by a composite structure consisting of individual elements. The deformation of elastic checking units is determined by the components of local elastic generalized displacements and generalized reactions at the junction points of the elastic checking units. A diagnostic scheme for load-bearing structures using elastic checking units is considered. This diagnostic scheme can be performed in laboratory and field conditions.
