ISEE Application on a Transnational Pseudo-dynamic DSCFT-Pier Experiment

This short report introduces the upgrades of a networked experimental platform, ISEE(Internet-based Simulation for Earthquake Engineering) and its application on a Taiwan-Canada collaborative experiment of a bridge system. Based on the networked pseudo-dynamic experiment technology, this experiment simulated the dynamic responses of a five-span double-skinned-concrete-filled tubular(DSCFT) bridge subjecting to a series of ground motions. Three of the four DSCFT piers were separately located and tested simultaneously at NCREE, National Taiwan University and CU, while the remaining parts of the bridge were modeled and their responses obtained by dynamic time integration using either an extended OpenSees or an extended PISA3D computing environment following pseudo-dynamic analysis procedure. The Database Approach of ISEE platform was adopted to integrate the hardware and software units in the three laboratories, and broadcast in real-time the progress of the transnational hybrid tests of instant videos, data plots of numerical and experimental data, and visualization of the bridge deformations. This report is a short version of a paper published in the 8th National Conference on Structural Engineering in Taiwan(Yang et al., 2006A).
