Abstract:
The authors of the Report dealing with study of strength and strain characteristics of stay-in-place steel-fiber-reinforced concrete ((SFRC) forms also performing, in process of reinforced concrete structure operation, the functions of load bearing element analyzed the issue of effects of high temperatures occurred during fire on strength of SFRC of the forms and on rate of ultrasound propagation in forms. The results of study may be taken as a basis for development of recommendations for assessment of technical condition of reinforced concrete structures after fire.
