| dc.description.abstract1 | The direct tensile test (DTT) is the most recommended test to determine the tensile behavior
of fiber-reinforced concrete (FRC). However, this test is challenging to perform. Several studies
have investigated inverse analysis to determine this behavior through simplified tests, such as the
bending test. This study deals with developing a new approach to perform an inverse analysis for
the three-point bending test (3PBT) involving FRC. A new proposed methodology concerns carrying
out the inverse analysis procedure by parts. Initially, the parameters that influence the initial part
of the stress–crack opening curve are adjusted. Progressively, the other parameters are adjusted
considering the increment of the curve section. This procedure provides an implemented algorithm
with more efficiency. A new strategy that deals with the establishment of criteria for parameters is
proposed. Its results are compared with experimental data from other literature, whose steel fiberreinforced concrete (SFRC) tested characteristics present different attributes such as fibers, shape, and
length. The proposed methodology obtained the stress–crack opening curves in direct tension with
reasonable accuracy, indicating that this methodology can be helpful in the characterization of the
post-cracking FRC behavior. | pt_BR |
