Tensioning device, e.g. steel cable, stress controlling process e.g. for concrete pre-stressed structure, involves observing displacement of target point of tensioning device from point of observation in structure, along contour of device
Tensioning device stress controlling process involves observing the displacement of a target point pertaining to one of tensioning devices, from a point of observation in a pre-stressed structure along the contour of the tensioning devices. The observation point has a hollow cylinder between the structure and the device presenting the target point. The cylinder is formed with the construction of the structure or by drilling the structure. An independent claim is also included for a pre-stressed structure.
