Beam2Beam

Beam2Beam is an online calculator for two‑dimensional structural frames. It allows users to define nodes with coordinates, assign external constraints such as fixed, hinged, roller, pendulum or double pendulum supports, and specify internal constraints. Users can also input member properties—elastic modulus, cross‑sectional area, and moment of inertia—along with nodal forces, moments, distributed loads, springs, and settlement conditions.

The tool performs static analysis, computing reaction forces, axial forces, shear forces, bending moments, and deformations for each member. Results are presented interactively, with options to view diagrams of internal forces and to display maximum and minimum values. After solving, the generated structural diagram can be exported in a CAD‑compatible format for further use.

Beam2Beam targets students, educators, and professionals who need a quick, free solution for basic 2D frame analysis without installing software. Its web‑based interface and direct CAD export make it suitable for rapid prototyping and instructional demonstrations.
