The PGSuper Resource Center is the premier online hub dedicated to supporting users of PGSuper, the industry’s most comprehensive open-source software for precast-prestressed girder bridge design. The platform offers a blend of free documentation, specialized training tutorials, and collaborative community boards aimed at structural and bridge engineers.
“Join the Conversation on Girder Design” is the center’s core interactive initiative, designed to foster peer-to-peer knowledge sharing, bridge the gap between automated software constraints, and solve complex real-world bridge engineering problems. Key Features of the Resource Center
Interactive Forums: Engineers collaborate globally to troubleshoot code compliance issues, check AASHTO LRFD specifications, and debate regional Department of Transportation (DOT) library configurations.
Advanced Video Tutorials: The platform offers training on critical engineering roadblocks. For example, the popular Advanced Girder Design Example tutorial teaches engineers what to do when automated algorithms generate unusable designs. It explores manual adjustments like swapping straight strands for harped patterns, balancing excessive release strength, and adjusting haunch/slab offsets.
Library Management: Users can access and download pre-configured master libraries, allowing them to import custom girder entries (such as standard Caltrans or Texas DOT I-girders) directly into their projects.
Professional Tier Integration: The resource center hosts exclusive documentation for PGSuper Professional (managed by BridgeSight Inc.), which adds features like 3D visualization, a unified Girder Design Dashboard, and data exchange tools for Excel, LandXML, and DXF. Core Discussion Topics on the Platform
The engineering conversation in the community center typically revolves around overcoming software automation limits and addressing physical structural boundaries:
Algorithm Failures: Learning to recognize when PGSuper’s automated designer produces a failing specification check (such as compression stress failures at release) and how to fix it by hand-tuning the strand arrangement.
Complex Geometrics: Discussing how to accurately model highly complex roadway profiles, including splayed girders, three-span tapered layouts, and horizontal or vertical roadway curves.
Construction Stages: Exchanging techniques to safely analyze girders through all critical temporary boundary states—from casting, lifting, hauling, and erection, to final service conditions.
If you are working on a specific bridge model, feel free to share your girder type, your target DOT specifications, or any failing spec checks you are encountering so we can look at potential troubleshooting options.
