摘要:
利用自行研制的三向强度变形试验装置,进行了应力比α=σ1313=0:-1,0.05:-1,0.1:-1,0.2:-1和0.3:-1的拉-压平面应变状态强度与变形试验.试验结果表明:在拉-压平面应变状态时,混凝土破坏形态主要分为受拉和受压2种,应力比α=σ13≤-130.1时为受拉破坏,应力比α>-0.1时为受压破坏; 在混凝土开裂或屈服前,应力-应变关系呈线性.同时,根据试验结果给出了拉-压平面应变状态的强度计算公式,完善了平面应变状态等效单轴应变本构模型.
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.
