The verification of a new approach to the experimental estimation of tensile forces in prestressed structural elements by method based on the magnetoelastic principle

摘要

There are a large number of civil engineering structures where the important structural elements are loaded by large tensile forces. In many practical cases, it is significant to know the current value of tensile force or prestressed stress in these elements for accurate assessment of the reliability of the whole structure. The brief principle and the basic validation results of the new approach to the experimental estimation of tensile forces or stress in prestressed structural elements of engineering structures by the method based on the magnetoelastic principle are described in the paper. The new approach was designed and developed especially for application on existing prestressed concrete structures.
