The beam calculator also allows cantilever spans at each end, as the position of the first support does not have to be equal to 0mm and the last support position does not have to be equal to the length of the beam. A minimum of one fixed support, or two pinned supports are required. The support type can either be pinned (fixed in translation, free in rotation) or fixed (fixed in both translation and rotation) and is selected from the drop-down menu. Position of Supports from Left allow the user to input any number of supports, and specify their position along the length of the beam. Alternately, you can create your own custom section using our free moment of inertia calculator. The properties E, A, and Ix for other beam sections can be obtained from the ClearCalcs section properties library. Second Moment of Area (or Moment of Inertia) is also specific to the beam section selected, and again defaulted to the properties of a common steel beam. Young’s Modulus is set to a default value of 200,000 MPa or 29000 ksi for structural steel, but can be edited by the user.Īrea of the Cross-Section is specific to the beam section selected, and is defaulted to the values for a common steel beam. Length of Beam is the total including all spans of the beam, in mm or ft. The properties of the beam and section are specified by typing directly into the input fields. Clicking on any of the input/property labels gives a descriptive reference explanation. ‘Summary’, which displays the key outputs and diagrams.Ī ‘Comments’ section is also included for the user to leave any specific design notes.

‘Loads’, where the use can input distributed, point and applied moment loads,.‘Key Properties’, where the user inputs the geometry of their chosen section and the beam supports.The sheet is divided into three main sections: ClearCalcs enables design in steel, concrete and wood, according to Australian, US and EU Standards. Signing up for a ClearCalcs account will unlock further advanced features for design and analysis of beams and a variety of other structural elements. It then determines bending moment, shear and deflection diagrams, and maximum demands using a powerful finite element analysis engine. The ClearCalcs beam calculator allows the user to input the geometry and loading of a beam for analysis in a few simple steps. Integrating curvatures over beam length, the deflection, at some point along x-axis, should also be reversely proportional to I.How to Use The Free Beam Analysis Calculator Therefore, it can be seen from the former equation, that when a certain bending moment M is applied to a beam cross-section, the developed curvature is reversely proportional to the moment of inertia I. Therefore, the moment of inertia I x of the tee section, relative to non-centroidal x1-x1 axis, passing through the top edge, is determined like this: The final area, may be considered as the additive combination of A+B. Sub-area A consists of the entire web plus the part of the flange just above it, while sub-area B consists of the remaining flange part, having a width equal to b-t w. The moment of inertia of a tee section can be found if the total area is divided into two, smaller ones, A, B, as shown in figure below.
