Stress-strain state investigation of Yusupov kinematic supports by means of Lira-SAPR

The article investigates the stress-strain state of the three types of Yusupov kinematic supports, which differ in the geometry of the contact surface. A design scheme that implements the interaction of the support with the structural elements of the building as a contact with friction is used. Recommendations on defining stiffness properties of two-node finite elements of LIRA-SAPR simulating one-way interaction (with friction) of kinematic support with building elements; on setting the iterative process' parameters of solving structurally non-linear tasks to provide the equilibrium of the plate and the kinematic support are given.
