Graphical 3D Visualization of Highway Bridge Ratings
Aging highway infrastructure requires effective rating methodologies to prioritize bridges for rehabilitation and repair. To aid engineers in decision making regarding bridge maintenance, a three-dimensional 3D visualization system is developed for rating reinforced concrete deck-girder bridge. Color codings show the most probable mode of failure for girder cross sections under combined moment-...
متن کامل3d Highway Landscape Modeling and Visualization
In this paper, data model and structure of the 3D road model, which is constructed by Constrained Delaunay Triangles (CDT) and integrated with terrain model, are proposed first, and the method of judging the maximum angle was used to build the triangle net. Considering the characters of strip-distributed and data volume of highway, the following two methods are developed to enhance the 3D roami...

متن کاملEvaluation of Highway Bridge Strength Considering Parapets
This paper describes a study evaluating increase in design strength, performance and capacity when including bridge parapets in a bridge analytical model. Traditionally, concrete parapets are treated solely as superimposed dead load in an overall bridge structural design. Parapets are detailed from a safety standpoint to resist impact forces from vehicle loading. However, in the global design m...
متن کاملIntegrated 3D Bridge-Condition Visualization (BCV) to Facilitate Element-Based Bridge Condition Rating (EBCR)
Routine inspection and maintenance records are essential for bridges to function well throughout their intended lifespan. Although existing bridge management systems are efficient at data storage, it is difficult to conduct comprehensive data analysis and management due to the lack of data integration mechanism. Engineers have to manually put many pieces of bridge drawings and inspection data t...
