Resumo: | |||||||||||||
The application of high-performance concrete as a
construction material is becoming increasingly
common in conventional concrete structures. This trend
demands a better knowledge of the
material, besides the parameter that refers to the limit
stress in compression. Being a relatively
new material, with a known brittle behavior, few
information about its performance is available
for design engineers that allows the correct design of
special structures. As the material provides
a higher compressive strength, concrete structural members
can increase in size, allowing the
reduction of the number of columns in a building, for
example. In this case, the fracture
mechanics size effect should be considered in the
structural design, and the fracture energy turns
to be a fundamental property in controlling the flexural
and shear strength of the concrete
structural members.
In this dissertation, some results obtained through
experimental tests for determination of fracture
energy for high-performance concrete are presented. The
three-point bend tests were conducted at
PUC-Rio for different compositions of concrete, with
compressive strength equals to or greater
than 40 MPa. The tests comply with the specifications given
in RILEM recommendations,
RILEM 50-FMC and were performed in a servo-controlled
materials testing system. The
compositions of the concrete were established in order to
match the concrete commonly used by
the companies that operate in Brazil.
