The in Situ Application of a New Approach to Experimental Estimation of Tensile Forces in Prestressed Structural Elements by Method Based on the Magnetoelastic Principle

Original language description

The important structural elements loaded by great tensile forces (prestressed reinforcements of concrete bridges for example) significantly affect the reliability of the whole structure. The force in such element fluctuates considerably in time. Accurate information about the current force value is very important for exact assessment of the structural reliability at any of the life cycle stages of the structure. The five experimental approaches are most often applied for determination of axial tensile forces in civil engineering practice. They are the direct measurement of the force by a pre-installed load cell, the approach founded on a strain measurement with strain gauges, the force determination in a flexible structural element based on the relation between the transverse force and the caused transverse displacement, the vibration frequency method and the magnetoelastic method. At first, the advantages and disadvantages of the above mentioned approaches have been discussed in the paper. Subsequently, the basic principles, results of the experimental verification and the in situ application of the new approach to experimental estimation of tensile forces by the method based on the magnetoelastic principle are described.
