Modeling Transition in Design Model when Analyzing Specific Behaviors of Structures

This paper explains the basic principles related to design prediction for stress-and-strain state of load-bearing structures taken into account the stage-wise closing of the load-bearing structures system and changing the stiffness properties for members of the design model, external constraints, time histories of the pattern and values of loadings, time histories of nature of interaction between foundation- mounted load-bearing structures and foundation structures.
