Enhanced Multi-Site Hybrid Simulations Using an Internet-based Grid System for Construction and Civil Engineering Facilities

KOCED(Korea Construction Engineering Development) is formed to provide a shared infrastructure for construction and civil engineering facilities across Korea. Users can perform remote experiments on these distributed facilities using the KOCEDgrid, which is an Internet-based grid computing system. We present technologies to support enhanced hybrid simulation on the KOCEDgrid. A new realtime controller and viewer provide a user-friendly interface to an enhanced environment for hybrid simulation, which has been built on a new version of the grid middleware and on a new hybrid modeling tool. Users can now conduct experiments more flexibly and combine more than one piece of experimental equipment. The elimination of unnecessary communication overheads has reduced simulation times.
