The example below shows the outputs for a two-span continuous beam with a linear distributed patch load and point load. Using the cursor to hover over any point on the bending moment, shear force or deflection diagrams gives the specific values at that location along the beam. The sign convention used in the shear force and bending moment diagrams is (positive values shown): Positive values imply a downward deflection and negative values imply an upward deflection. The maximum values of each are output as ‘Moment Demand’, ’Shear Demand’ and ‘Deflection’, along with the diagrams along the length of the beam. Once the loading and geometry have been specified, the calculator automatically uses the ClearCalcs finite element analysis engine to determine the moments, shear forces and deflections. The sign convention used for loading is (positive values shown): The calculator supports a variety of different loading types which can be applied in combination. The reactions at each of the supports are automatically updated as supports are added, changed or deleted, based on the specified loading. 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. The tables contain next to second moment of inertia data about section modulus, geometrics, cross sectional area and more.How to Use The Free Beam Analysis Calculator Standard universal steel beamsĪt the bottom of this page several tables are placed containing data of standard universal beams. It is common for the second moment of inertia to be confused with the mass moment of inertia that indicates the resistance to acceleration of an object. The polar moment of inertia is determined from the same geometric input and is used in torque calculations. For this, the second moment of inertia is divided by the outer fiber distance seen from the neutral line. The calculators on this website assume that the element always bends around its neutral line which runs across the gravitational center of the cross section.Ĭlosely related is the section modulus which is used to determine stress at a certain load.

The outcome of the calculation can be used to determine the response of an element to a particular load. The second moment of inertia is independent of material and environment and is purely determined by geometric values of the element. The unit used for the 2 nd moment is length to the fourth power (m 4). Other (more) correct names are moment of inertia of plane area, area moment of inertia, or second area moment.

The second moment of inertia indicates the resistance to deflection of a particular section of a profile or beam.
