Abstract:Taking advantage of the grid technique in open framework, general criterion, and standard middleware technology and so on, this paper proposed remote structural-state-evaluation system for bridge based grid, in which the distributing resources of structural state evaluation were defined as grid services, and under the management and control to evaluate the status of bridge.It designed grid service model based semantic Web to support formal modeling of grid service. By integrating Globus Toolkit 4 (GT4) middleware, also developed grid service manage module (GSMM) to provide functions for registry, discovery and so on. Furthermore, developed grid task manage module (GTMM) based agent technique to performs structural-state-evaluation task disassembling, scheduling and so on. Taking structural health monitoring for the Dongting Lake Bridge as application background, developed a prototype system. Practice shows that the system is able to offer effective way to apply the structural health monitoring. ......
