Abstract
Diagnostic load testing techniques have been used to verify in situ that existing structures have the required load-carrying capacity. This paper discusses the diagnostic load testing and finite-element modeling of a two-way posttensioned concrete slab with the purpose of illustrating the features of this full-scale testing method. The slab was modeled using a commercial finite-element package and the results were verified experimentally. The test loads were applied using hydraulic jacks. Negative internal bending moments were generated at critical locations equivalent to those produced by a 92 psf (4.40 kPa) superimposed uniformly distributed load. Positive internal bending moments were also produced equivalent to those resulting from a superimposed load of 159 psf (7.61 kPa). The full-scale diagnostic load testing proved to be a valuable tool for the assessment of the structure's capacity.
