Abstract
As an extension of the conventional online hybrid tests, the Internet online hybrid tests combine multiple loading tests conducted in remote locations and integrate the tests with sophisticated numerical analysis codes. In this paper, three frameworks for the Internet online hybrid tests, designated as host-station, dual-model, and peer-to-peer frameworks, respectively, are presented. The host-station framework incorporates a user-defined experimental element into the numerical model for the entire structure. The dual-model framework solves the dynamics of the entire structure separately from the static tests and analyses for the substructures. The peer-to-peer framework is more extensible, dividing the entire structure into encapsulated substructures with a generalized interface. Multiple tested substructures and numerical substructures using various structural analysis codes can be accommodated within the single framework, simply interfaced with the boundary displacements and forces. Coordinator programs are developed to keep the boundaries among all substructures compatible and equilibrated. A series of online hybrid tests are conducted and the online hybrid test frameworks are demonstrated to be flexible, extensible and accurate.
