Abstract EN
Concrete cracking strength can be defined as the tensile strength of concrete subjected to pure tension stress.
However, as it is difficult to apply direct tension load to concrete specimens, concrete cracking is usually quantified by the modulus of rupture for flexural members.
In this study, a new direct tension test setup for cylindrical specimens (101.6 mm in diameter and 203.2 mm in height) similar to those used in compression test is developed.
Double steel plates are used to obtain uniform stress distributions.
Finite element analysis for the proposed test setup is conducted.
The uniformity of the stress distribution along the cylindrical specimen is examined and compared with rectangular cross section.
Fuzzy image pattern recognition method is used to assess stress uniformity along the specimen.
Moreover, the probability of cracking at different locations along the specimen is evaluated using probabilistic finite element analysis.
The experimental and numerical results of the cracking location showed that gravity effect on fresh concrete during setting time might affect the distribution of concrete cracking strength along the height of the structural elements.
