How to Use the Frame Analysis Calculator - Step by Step
1. Model Frame Geometry
Define frame nodes by specifying X and Y coordinates for each joint location. Connect nodes with beam and column elements to create your 2D frame structure. Set material properties and cross-sectional dimensions for accurate structural analysis.
2. Define Support Conditions
Specify support types at foundation nodes: fixed supports (prevent all movement), pinned supports (allow rotation), or roller supports (allow horizontal movement). Support conditions determine how the frame connects to foundations and affects structural behavior.
3. Apply Loads and Forces
Input point loads at nodes with magnitude and direction specifications. Add distributed loads on frame elements for uniform pressures or self-weight. Apply concentrated moments where required for complete loading representation.
4. Execute Matrix Analysis
The frame solver automatically processes the structure using matrix stiffness methods. Advanced algorithms solve equilibrium and compatibility equations simultaneously. Analysis handles indeterminate frame structures with professional-grade accuracy and speed.
