Integration of OpenSees Data Models in 3D WebGIS for Bridge Monitoring

In this paper I present a system for integration, visualization, and simulations in a 3D WebGIS environment of analysis models performed in OpenSees. The currently available FEA/FEM post-processor environments are still in the local environment due to the limited ability to navigate and interact with the model in open environments such as the web. Visualization and simulation techniques have evolved significantly over the past few decades and have become indispensable for interpreting finite element output data. These products are, however, proprietary, which eliminates user potential and extensions because the source code is not publicly available. OpenSees is an open source analysis platform well known in earthquake engineering research because it provides a powerful solver with many standard and constitutive material models, finite element types, boundary conditions, and analysis capabilities. A large number of researchers are actively contributing to its development and innovative features. Visualization and simulation through a GUI is important, for these reasons we present a system to integrate and visualize in a 3D WebGIS environment the models generated in the OpenSees environment and distribute them in a web environment through the browser, with the possibility to have a user friendly environment to verify the simulations obtained and disseminate them to a large number of users. The main properties of structured data in the OpenSees environment for linking data structurally through metadata are presented.
