Abstract

The paper present the results of reinforce concrete beams damaged at compressed fiber. Study of damaged reinforced concrete elements is associated with certain complexity in both theoretical and practical issues. In such cases the number of factors take place which influence on elements’ performance, which is caused by composite features of reinforced concrete elements. In addition certain factors occur due to damages. In the article experimental data is analyzed concerning concrete damages’ influence in the compressed zone on the bearing capacity of the reinforced concrete elements. Results of 4 reinforced concrete beams’ testing are proposed one of which was the control one (tested without damages) and three,- typically damaged in compressed zone at different load levels. As the result the effect of damage and load influence on bearing capacity of beams was indicated, as well as effect of neutral axis position change. Research results demonstrate increase of 3.8% in reinforced concrete beams bearing capacity, if they are damaged under the load, comparing with the unloaded damaged reinforced concrete beams.
