摘要：A method and system are described for tensioning structural strands 1 of atendon in a duct. Each strand 1 is fitted with its own load cell 22, so that the individualtension values in each individual strand 1 can be measured during the tensioning of thestrands 1. The load cells 22 may be removed after tensioning, or left in situ to enableongoing monitoring of the tension in the strands 1. The load cells 22 may be calibratedsimultaneously by tensioning the strands 1 to an equal tension using individual jacks 10,then normalizing the signals from each load cell 22 to the known equal tension value. Afurther calibration to a global strand load measurement may also be performed.
