Tempiamojo betono įtempių ir deformacijų priklausomybės tyrimas ilgalaikio apkrovimo atveju ; Analysis of Stress-Strain Relationship of Tensile Concrete in the Case of Long-Term Loading
The paper suggests tension concrete stress-strain dependence of the short-term and long-term case-load of the EC2 method. Bending reinforced concrete elements of stress and strain dependence are analyzed. Presented overview of such elements deformation calculation methods and mathematical models, highlight the relevance literature review, relating to bending reinforced concrete elements. Collected bending reinforced concrete elements (numerical experiments) data, examined short-term and long term effects of load to bended reinforced concrete elements, deformations and the determining factors, performed their analysis. For the purposed of VGTU bridges and special structures department’s constitutive model from the numerical experiments obtained moment-curvature relationships derived the charts of cracked pulling concrete stress-strain dependence. Choose the basic theoretical parameters of the relationships, depending on the class of concrete, reinforcement rates, and creep coefficient. The calculation results are compared with the experimental beam data. Performed calculation results of the analysis showed quite accurate results with the derived dependencies.
