An experimental program for structural engineering application

Beam calculator


Purpose: compute/plot: deflection, slope, bending moment, and shear diagrams

Input data for beam properties:
 Beam span length (m)   L =  12
 Beam's section area moment of inertia (x 10-6 m4  I =  50.0
 Young's modulus (x 109 N/m2  E =  200.0

   Case 4   
NA
   Case 5   
NA
   Case 6

Multiple loads (max. 2 point, +2 UDL, and +2 bending loads) can be superposed on this beam.

Point loads


NA
Input data for 0-2 point loads:
    #1  #2   ← check/uncheck to include/exclude load(s)
 Point load (kN)  P =    10.0   10.0  ← check to signify negative value of P
 ← slide to get the desired value of P
 ← current value of P (kN)
 Distance from left (m)   a =  0.5 1.0  ← slide to get the desired value of a
 ← current value of a (m);  a ≤ L

Uniformly distributed Loads (UDLs)


NA
Input data for 0-2 distributed loads:
    #1  #2   ← check/uncheck to include/exclude load(s)
 Uniformly distributed load (kN/m)  q =   ← check to signify negative value of q
 Left unfilled distance (m)   a =   a+b < L
 Right unfilled distance (m)   b =   a+b < L

Point bending moment loads


NA
Input data for 0-2 bending moment loads:
    #1  #2   ← check/uncheck to include/exclude load(s)
 Bending moment load (kN.m)  M =   ← check to signify negative value of M
 Distance from left (m)   a =   a ≤ L
