The article shows the main results of experimental research flexible rod composite reinforced concrete structure with sheet steel framework. When conducting experimental studies of researched the peculiarities of constructions under load and nature loss bearing capacity composite reinforced concrete structure samples with external steel framework with steel plates depending on the eccentricity application of efforts. Common to all samples is that under load was hogging the long axis of the element. This led to an uneven distribution of longitudinal deformations in reinforcement sheet, and accordingly, the wrinkles were formed by the opposite direction of bending. The results showed that the compressed-noncentral elements as limiting load advisable to take two values: the first corresponds to the limit efforts to achieve the most intense fiber sheet reinforcing fluidity limits of steel; second – the moment destruction test sample in which there is intense curvature of the longitudinal axis.
