It can also be used as a beam load capacity calculator by using it as a bending stress or shear stress calculator. Use the 'Optimize' tab to change your chosen section size based on criteria you can choose. Use the sign convention to determine the direction of the shear force, where positive shear force is assumed to act upwards and negative shear force is assumed to act downwards. When beams carry loads too heavy for them, they start to bend. Loads, on the other hand, affect the beam's deflection in two ways: the direction of the deflection and the magnitude of the deflection. A long night of studying? Beam Load Calculator Per. Length of beam : meters. Concrete's modulus of elasticity is between 15-50 GPa (gigapascals), while steel tends to be around 200 GPa and above.
