Cyclic Load Tests of Composite Prestressed Reinforced Concrete Panels by Howard L. Furr and Leonard L. Ingram The use of stay-in-place prestressed concrete panels as forms for an upper layer of bridge deck concrete has raised questions about

The traditional P-wave ultrasonic measurement has been used for the condition assessment of general reinforced concrete structures for a long time, but the effects of prestressing applied to concrete structures such as long-span buildings and bridges on ultrasonic pulse velocity have not been studied clearly. Therefore, this study analyzed the statistical distribution of P-wave ultrasonic
