We present to your attention an online calculator for calculating beam strength. With its help, you can quickly and accurately calculate the parameters of a wooden or steel beam.
The calculator allows you to:
Set the beam length L and choose the load type: uniformly distributed load q or concentrated force P.
Select the beam material: steel (S235, S275, S295, S420) or wood of three different grades.
Specify the geometric dimensions of the cross-section, providing the ability to calculate various types of beams: pipe, channel, structural tube, I-beam, angle, plate, and others.
Select the support configuration: hinge-hinge, fixed-hinge, fixed-fixed, or free end of the beam.
During the calculation, the following factors are considered:
Normal stresses from the bending moment.
Shear stresses from the transverse force, calculated using the Jourawski formula.
Verification by the third strength theory using principal stresses.
For wooden beams, correction factors for the design bending resistance are applied:
Mdl = 0.66 — combined effect of permanent and short-term snow loads.
Mv = 0.9 — normal operating conditions for wood (moisture content less than 12%).
Mt = 0.8 — operation at a temperature of 50 degrees Celsius.
Mss = 0.9 — service life of the structure is 75 years.
This online calculator will be an indispensable tool for engineers and builders, allowing them to quickly calculate beam strength and optimize the design of structures made of steel and wood.
