Abstract:
Tests of concrete in tension-compression plane strain are carried out using the apparatus for multi-axial performance of concrete designed by the authors. The stress-strain curves are obtained with the stress ratios α=σ13=130:-1,0.05:-1,0.1:-1,0.2:-1, 0.3:-1. From the experimental results, it can be concluded that the failure modes of concrete can be classified into two categories: compression failure when α>-0.1, and tension failure when α≤-0.1. The stress-strain relation is approximately linear before cracking or yielding of the concrete. Meanwhile, according to experimental results a strength formula for concrete in tension-compression plane strain is presented, so that the equivalent uniaxial constitutive model of concrete in plane strain is improved.
