Make use of our beam deflection calculator to find maximum deflection of the beam (simple-supported or cantilever) after a certain load is carried on it. Calculates the effect of beam bending depending upon the magnitude and location of the object placed on it.
Following beam deflection formulas will help you out in determining the respective beam deflections for certain loads it carries:
\(𝛿_{max}=\dfrac{PL^{3}}{48EI}\)
\(𝛿_{max}=\dfrac{Pb\left(3L^{2}-4b^{2}\right)}{48EI}\)
\(𝛿_{max}=\dfrac{5wL^{4}}{384EI}\)
\(𝛿_{max}=\dfrac{0.00652wL^{4}}{EI}\)
\(𝛿_{max}=\dfrac{wL^{4}}{120EI}\)
\(𝛿_{max}=\dfrac{ML^{2}}{9\sqrt{3}EI}\)
For these specific types of beam, our steel i beam deflection calculator different equations that are as follows:
\(𝛿_{max}=\dfrac{PL^{3}}{3EI}\)
\(𝛿_{max}=\dfrac{Pa^{2}\left(3L-a\right)}{6EI}\)
\(𝛿_{max}=\dfrac{wL^{4}}{30EI}\)
\(𝛿_{max}=\dfrac{11wL^{4}}{120EI}\)
\(𝛿_{max}=\dfrac{ML^{2}}{2EI})
The process is quite simple only if you go by the following operating guide to use this beam bend calculator!
