Beam Calculator

PolyBeam is a robust and user-friendly beam calculator that allows you to calculate sectional forces and reactions for statically indeterminate beams. This beam calculator relies on the principles of linear elastic finite element theory.


Determining the beam's fire-resistant capacity is straightforward and based on the desired fire duration and the sides exposed to the fire. When dealing with steel beams, it's a simple task to identify the required fire protection by using the critical steel temperature calculated by PolyBeam.


Documentation is growing in significance within structural design, and PolyBeam is purpose-built with this in focus. Crafting a document is effortless, requiring just a few clicks, and it's designed to be both succinct and precise. When complemented with graphical illustrations, this approach simplifies quality control procedures.

Ultimate Limit State

Assess the load-bearing capacity of your steel, timber, and concrete beams according to Eurocode standards. PolyBeam employs advanced calculation techniques to optimize material usage effectively.
PolyBeam accurately determines the critical bending moment through precise geometric eigenvalue calculations. This eliminates the need for manual buckling length assessments, reducing the risk of errors. As a result, PolyBeam often results in significantly enhanced load-bearing capacity compared to conventional methods.

Serviceability Limit State

With PolyBeam, you can examine deflection and natural frequency for steel, timber, and concrete beams in the serviceability limit state. Specifically for concrete beams, you can also assess crack width and reinforcement stress.
The calculations of concrete beam incorporate varying stiffness along the beam, determined by moment distribution. This approach minimizes deflection, making it especially advantageous when deflection governs the design.
