Abstract In order to establish a more rational structural design method for mortar-filled sleeve rebar splices, it is necessary analyze and evaluate factors affecting the performance of these splices. It very desirable be able quantitatively estimate failure mode splices at stage. A estimating presented from existing research not clear because boundary expressed in formulas. There are also limi...

This paper investigated experimentally the feasibility of the method to estimate the stress in the prestressing tendons of prestressed concrete bridges using the magnetic field induced by a moving electromagnet. This method is based on the Villari effect in which the magnetic permeability of prestressing tendons changes when subjected to a mechanical stress. The test results show high linearity...
