Kalmikov Y. Volumetric stress-strain state of rod reinforced concrete units at one-time heating up to +150 С

The work is devoted to the development of computational method of stress-strain state of reinforced concrete structures on temperature and humidity gradients influences and loads with allowance for volumetric stress. The experimental research of influence of sizes and conditions of drying of specimen on stress and strain haracteristics of concrete at an axial compression, including heating up up to 150°C are carried out. Data on change of strength and strain concrete properties on volume of large size specimens with different conditions of drying are obtained. The experiments on concrete orthotropic deformation characteristics under uniform (hydrostatic) and nonuniform tri-axial compression, including heating up to +150°C, are carried out. The results of numerical researches of volumetric stress-strain state of reinforced concrete units concerning rod structures of industrial buildings, as well as structural elements of reinforced concrete engineering buildings are obtained.
