About SAS2D
What is SAS2D?
SAS2D (Structural Analysis System - 2D) is a web-based application for analyzing 2D frame and beam structures using the displacement method (also known as the stiffness method). It provides an intuitive interface for structural engineers, students, and educators to model, analyze, and visualize structural behavior.
Purpose & Target Audience
- Students: Learn structural analysis concepts through interactive visualization
- Teachers: Demonstrate structural behavior and analysis methods in class
- Practitioners: Quickly analyze simple 2D structures for preliminary design
