Everything you need to know about Frame Solver

What is Frame Solver?

Frame Solver is an online calculator specialized in structural analysis of plane frames and portal structures. It uses matrix methods to solve statically indeterminate structures, calculating reactions, bending moments, shear forces and displacements. Perfect for engineers, students and structural professionals.

Supported Structure Types

Analyze single or multi-story portal frames, simple frames, portal structures and complex configurations with beams and columns. Supports different support types: fixed, pinned and simple supports. Ideal for buildings, industrial structures and civil engineering applications.

Loads and Actions

Apply point loads at nodes and elements, distributed loads on beams, and concentrated moments. Combine different load types to simulate real conditions: dead loads, live loads, wind loads and simplified seismic actions.

Detailed Results

Get reactions at all supports, bending moment and shear diagrams, nodal displacements and rotations. Results include precise numerical values and clear graphical representations. Information ready for calculation reports and structural verifications.

For Engineering Students

Essential educational tool for structural analysis, concrete and steel design courses. Visualize concepts of stiffness, equilibrium and deformability. Perfect for verifying matrix analysis exercises and understanding behavior of framed structures.

For Professionals

Quick validation of preliminary sizing and preliminary analysis. Useful in conceptual stages where different structural configurations are evaluated. Complements specialized software providing independent verifications and sensitivity analysis.

How to use Frame Solver step by step

1. Model the Geometry

Define the nodes of your structure specifying X and Y coordinates. Connect nodes with beam or column elements. Set geometric and material properties for each element.

2. Define Supports and Restraints

Specify the support type at each node: fixed (restrains translation and rotation), pinned (allows rotation) or simple support. Restraints determine how the structure connects to the foundation.

3. Apply Loads

Input point loads at nodes specifying magnitude and direction. Define distributed loads on elements specifying intensity and application length. Add concentrated moments where necessary.

4. Run Analysis

The solver processes the structure through matrix stiffness analysis. The system automatically solves equilibrium and compatibility equations to obtain displacements and internal forces.

5. Review Results

Examine support reactions, bending moment and shear diagrams, and nodal displacements. Verify that results are consistent with expected structural behavior. Use values for element design and serviceability verifications.
