Influence of pre-stressing over parameters of diagram of static-dynamic deformation of RC elements

Abstract

The stress-strain state in RC elements of statically indeterminate structural systems under sudden restructuring is considered in this article. The solution of the problem on determining the parameters of a static-dynamic deformation diagram of prestressed RC elements was obtained on the energy basis excluding the structure dynamics instrument the problem. The deformation dependences for the pre-stressed flexural RC element are determined using the diagram method presented in the research of. For the possibility of obtaining an analytical expression of the desired moment convenient for practical application of the construction of the “moment-curvature” diagram for the pre-stressed element is performed using the simplest deformation dependence. The calculation analysis of the deformation of such a structural systems was performed using the level of primary and secondary design models.
