A Network Platform for Remote Pseudo Dynamic Testing

摘要

A network platform is developed for remote pseudo dynamic testing of substructures and structural elements. The network platform, NetSLab, was developed based on client/server concept along with a proposed data model and communication protocols. The platform is capable of transferring control and feedback data among remote structural testing laboratories or computers connected by Internet. Several concepts were introduced to realize the platform and to provide relatively easier and friendlier interface for applications and further development by users. Trial tests were successfully carried out at the Hunan University, China and the University of Southern California, USA. In the trial tests, models simulating bridge piers or piles were subjected to recorded earthquake ground motions controlled remotely over the Internet through the platform.
