calculator is developed to provide a software tool for calculation
Fixed-end Moments (FEM) ,
Moment and Shear Force at any section of
fixed-ended beam subjected to
point load, uniformly distributed load, varying load and applied moments.
Instructions for using Fixed Beam Calculator
(i). Sign convention
The loads acting
upward are considered as positive while the downward loads are taken
as negative. Sagging bending moment is
taken as positive and hogging as negative. The clock-wise rotation
are negative and anticlock-wise
(b) In case of Fixed-end moments, the
anticlock-wise moment at left-end support is taken as negative; it
will cause hogging moments in the beam, whereas at the right-end
support the clock-wise moment is taken as positive which causes
(ii) All the distances should be measured with
reference to the origin of axes which is taken at the extreme left
end of the beam. All the distances should be entered in meter and load in kN.
It will give the values of BM in kNm and SF in kN.
(iii) You can also quickly get the B.M. values
at different sections of the beam, just by changing the position of
(iv) In case of more than one load, take the sum of the
results of all the cases (apply principle of superposition). Calculated values can be used to plot the
bending moment diagram.
(v) This calculator can also be used to find the
ordinates of influence line diagram for
