NETWORKED COLLABORATIVE PSEUDO DYNAMIC TESTING EXAMPLES
Structural Stability and Dynamics
Currently, NCREE, through the use of the Internet, has constructed the Platform of Network Structural Experiment (PNSE). This platform allows structural laboratories sited at different geographical locations around the world to make full use of the Internet in transmitting experimental information promptly. Most importantly, it serves the function of allowing these laboratories to jointly carry out experiments. This platform also allows researchers around the world to visualize and take part in
... ze and take part in discussions of the undergoing experiments synchronously. This platform is constructed upon "Transmission Control Protocol/Internet Protocol (TCP/IP)", for diverse computer operating systems and working hardware, so as to attain the objective of integrating structural laboratories. The NCREE task group has developed an application for the communication protocol: "Network Structural Experiment Protocol (NSEP)", for the exchange of messages. Currently, the task group has performed several pseudo dynamic tests on a buckling restrained braced frame using the PNSE in order to verify the feasibility and the efficiency of the PNSE. The preliminary findings conclude that all the experimental and analytical data are transmitted accurately in the progress of testing and the experiment is accomplished successfully. However, there are still a lot of researches and developments can be done to improve the efficiency. At the time of this writing, structural laboratories at the National Center for Research on Earthquake Engineering (NCREE) and National Taiwan University (NTU) are in the status of preparing a joint pseudo dynamic testing on concrete filled steel tube columns.
