The effect of not repeatedly re-exposure to the compressive strength of concrete elements of expanded clay-fiber concrete. The experimental results of reinforced concrete columns after repeated unambiguous and alternating loadings. The influence of repeated loading regimes on the bearing capacity, deformation and fracture of columns. Proposed dependence of the bearing capacity of the columns on the level of repeated loadings.

The influence of non-multi - repeated loads on columns of keramzito fibrobetona. Comparative results of tests Depends on the flexibility of columns, the eccentricity of the external force, the coefficient of reinforcement options and loading. The obtained results suggest that repeated loading nemnogokratno increase the carrying capacity of columns, compared with a single loading. This is especially effective for columns with low flexibility and small eccentricities external force.
