Monitoring prestress levels during konstruktion is essential to ensure the safety and integraty of prestressed concrete structures. Accurate measurement helps detect deviations from design specifications and prevents potential failures. Various metods are employed to track theselevels effectively thout thee konstruktion process.

Strain Gauges

Strain gauges are common ly used to o melliure thee deformation of tendons or concrete under prestress. They are ataded directly to thee tendons or embedded with with in thoe concrete to providee real-time data. This methode offers high preciacy and is suablé for continous monitoring during tensioning and curing phases.

Load Cells

Load cells are devices installed in thoe stresssing equipment or along thee tendons to measure thee force applied during tensioning. They prove direct readings of prestress force, alloing equiphers to verify if thes desired levels are dosahován d. Proper calibration is necessary for precise mesticurements.

Ultrasonický Testing

Ultrasonic testing assesses the internal condition of concrete and tendons. By sending ultrasonicc waves impegh the material, it detects anotalies or changes in density that may indicate stress variations. This non- destructive methodis useful for ongoing quality control.
