Then, the stress–strain curve calculation model of concrete under a unidirectional load was used to describe the compression stress–strain curve of the plastic damage model, referring to the “Code for Design of Concrete Structures (GB50010-2019)” in China. The formulas are as follows: 𝜎...
This may be because the larger the pile diameter, the larger the contact area between the pile body and the soil body, and the smaller the stress on the soil body under the same area, which makes the difference in the displacement of the pile top under the conditions of calcareous sand ...

There is low scatter in the yield and tensile strength data, although a few stress-strain curves show abnormal behavior with reference to total elongation. Interestingly, the scatter in the impact toughness correlates to specific locations in the build height. The mechanical properties are important,...
Figure 6. Compressive stress–strain curves of specimens under full contact loading: (a) normal concrete (NC)-150; (b) crumb rubber concrete (CRC)5-150; (c) CRC10-150. 4.2. Environment Footprint In this paper, the impact of addition of rubber into concrete on the environment was also...
