Development of tool for estimating the diagram Residual Stress versus CMOD for the SFRC under 3BPT assay based on experimental results
Palavras-chave:

The three-point bending test, commonly used for the experimental analysis of a steel fiber reinforced
concrete beam (SFRC) involves difficulties, such as its cost of operation and mainly by the values of steel fibers
and test equipment. However, relatively few studies are done, especially in Brazil, and much remains to be done
for more accurate analyses of the results that corroborate each other. This study deals with the developing of a
practical algorithm that is easy to understand the user to provide expected results of a three-point bending test
based on experiments conducted by [1], [2] and [3]. The program was developed with the aid of the Matlab
software and stores the results obtained from the literature in the form of a database and returns to the user a
graph of Characteristic Residual Resistance (MPa) versus CMOD (mm).
