摘要: Post-tensioned tendon ducts in test specimens were investigated with scanning ultrasonic echo methods. For the same arrangement propagation of elastic waves was calculated 3D-EFIT order to understand wave such a multilayer system and for interpretation results. The results are compared aim improve reliability localising prestressed concrete structures indicate grouting faults inside. experiments modelling performed frame FOR 384 research group funded by Deutsche Forschungsgemeinschaft (German Research Council).
