    Abstract

    A servo-control system has been successfully installed on the universal panel tester to study the behavior of full-size reinforced concrete panel elements. In addition to the load-control procedure, this unique testing facility is now capable of testing panels using deformation-control procedure. This servo-control system controls up to ten different servo valves with independent programming capabilities and is thus suitable for many complex applications. By using this new servo control system we were able to determine, for the first time, some material properties of reinforced concrete, including Poisson ratios, the descending branch of compression stress-strain curves, as well as the characteristics of the compressive stress-strain curves of concrete in panels with 45° steel bars.
