Abstract

We present a grid-based system that enables researchers in civil engineering to conduct hybrid remote experiments as well as to record and replay these experiments. The system has been designed for Real Time Hybrid Testing Facility in the Korea Construction Engineering Development (KOCED) project and has been implemented based on the Open Service Grid Architecture (OGSA) and the Open System for Earthquake Engineering Simulation (OpenSees) for modeling and computational simulation on structural systems. Users can access the system with a Java client for data visualization and video monitoring through an Internet portal using a web browser. The system runs on a network of distributed NaradaBrokering streaming servers and exploits RFT and GridFTP for reliable file transfer. The main contribution of this paper is that we propose an scalable grid-based recording and replay architecture for remote experiment using distributed streaming network that can scale to support a growing large number of clients simultaneously. We also evaluate the performance of the proposed extensible architecture of distributed servers with mathematical modeling as well as simulations to show how it scales to cope with a growing large number of clients at the same time.
