BEAM FORMULAS WITH SHEAR AND MOMENT DIAGRAMS. Uniformly Distributed Load ... Beam Fixed at One End, Supported at Other – Concentrated Load at Any Point ...
Method. The starting point is the relation from Euler-Bernoulli beam theory ± = Where is the deflection and is the bending moment. This equation is simpler than the fourth-order beam equation and can be integrated twice to find if the value of as a function of is known. The slope of the shear diagram at a given point equals the load at that point. The maximum moment occurs at the point of zero shears. This is in reference to property number 2, that when the shear (also the slope of the moment diagram) is zero, the tangent drawn to the moment diagram is horizontal.
4. CASE 3 - SIMPLY SUPPORTED BEAM WITH POINT LOAD IN MIDDLE. Figure 4 The beam is symmetrical so the reactions are F/2. The bending moment equation will change at the centre position but because the bending will be symmetrical each side of the centre we need only solve for the left hand side. Fixed End Moments .

To apply the three-moment equation numerically, the lengths, moments of inertia, and applied loads must be speciﬁed for each span. Two commonly applied loads are point loads and uniformly distributed loads. For point loads P L and P R acting a distance x L and x R from the left and right supports,
Beam Formulas •Similar loading conditions = similar shear and moment diagrams •Standard formula can represent the magnitude of shear and moment based on loading condition •Magnitude of shear and bending moment depend on –Span length of beam –Magnitude of applied load –Location of applied load Beam Formulas •Similar loading conditions = similar shear and moment diagrams •Standard formula can represent the magnitude of shear and moment based on loading condition •Magnitude of shear and bending moment depend on –Span length of beam –Magnitude of applied load –Location of applied load
