Agentic Large Language Models for Automated Structural Analysis of 3D Frame Systems
TL;DR
Automated structural analysis of 3D frame systems has been limited by challenges in geometric representation and reasoning. A new agentic large language model (LLM) framework was developed to analyze 3D frames from natural language inputs, utilizing a multi-agent pipeline.
✦ Why It Matters
Engineers can leverage this framework to automate and enhance the accuracy of 3D structural analysis tasks.
Key Takeaways
- Utilize the framework for converting natural language to structural analysis inputs.
- Implement the multi-agent pipeline for efficient task management.
- Leverage the 90% accuracy in evaluations for reliable engineering outcomes.
- Explore the 2D projection method for representing complex 3D geometries.
How It Works
The framework uses a multi-agent system where each agent specializes in a specific task. For instance, the problem analysis agent converts natural language input into structured JSON format, while the floor decomposition agent organizes the spatial layout of each floor.
Geometry is constructed by agents responsible for nodes, girders, slabs, and columns, ensuring a comprehensive assembly of the 3D frame. Finally, loading conditions are assigned by dedicated agents, and the entire analysis is translated into an executable script for SAP2000, a structural analysis software.
