| Title of the article | Model of elastic behavior of concrete |
| Abstract. | To build a model of elastic behavior of the concrete model is adopted «matrix-filler». Model for probabilistic analysis conducted organize filler in the body of the matrix. Result: 1. Placeholder in the model is placed in a certain amount of it; 2. Filler shifted in accordance with stochastic processes; 3. There is minimum cell, where we get the inhomogeneous distribution of material; 4. Real model considers two types of heterogeneity – heterogeneity and heterogeneity between cells within a cell. Based on the analysis of the simplest models proposed three basic options for models. Distributed matrix with inclusions, rough. Aggregate – real or filler matrix defects. Using the model analyzed growth defects in the concrete (including cracks). Obtained a linear dependence of the number of defects due and initial modulus of elasticity of concrete E0/E0`= 1 - ?. Received different versions of dependencies: binding elastic properties of concrete (Eb), aggregate (EЗ) and matrix (EM). One of the most effective offered flat model. |
