Abstract

The introduction discusses the use of self - stressing concrete in reinforced concrete structures. The object of study is fiber reinforced self - stressing concrete. The analysis of the existing experience of using it in structures with various reinforcing elements is carried out. Positive effects have been noted when fibers are added to self - stressing concrete. The relevance of the topic under study is substantiated. It is noted that the empirical approach to estimating restrained expansion strains is not universal, therefore, the main direction that allows one to proceed to predicting properties and minimizing possible experimental studies is analytical and mathematical modeling. The existing models based on the deformation approach are analyzed. The distinctive features of the models for each case of limitation are given. The preconditions and assumptions of the modified strains development model for the case of a triaxial (volumetric) constraint are formulated. A modified model is proposed for determining the restrained expansion stresses and strains of self - stressing fiber - reinforced concrete at the expansion stage. The proposed analytical model can be used in design, educational and research institutions.
