One of the support questions we get most often is, “How can I model a cable element in RISA-3D?” Cables that are straight and experience only axial loading can be easily modeled.  When modeling structures with cables (such as guyed structures) the cables can be modeled as tension only and doing so will ensure that the member […]

For concrete column members, the load combination producing the maximum shear code check is reported in the Detail Report and corresponding Results spreadsheet. Since concrete is evaluated based on a batch solution, this can be useful when shear governs the design. RISAFloor Concrete tab of the Column Results spreadsheet: Column Detail Report: RISA-3D: Concrete Columns […]

RISA-3D now includes plate elements in the Material Takeoff. Plate elements are categorized by material, size (thickness), number of pieces, volume and weight.  The summation of total pieces, volume and weight is also available. We are continuously looking to improve the program.  If you are interested in providing feedback or suggestions for new features, please […]

There are many different types deflection values calculated by RISA-3D.  Let’s take a deeper dive into each. Absolute deflection is the maximum absolute value for deflection in the member local lateral y- and z-axis. In engineering terms, this value is also commonly referred to as global deflection since it encompasses the entire movement of a […]

RISA-3D v16.0.4 introduces an enhancement that will allow for more control over the beam deflection ratio through Deflection Ratio Options. As part of the member properties, you can now designate the ends of single and multi-span beams as a cantilever or supported. This will determine whether the beam deflection ratio is calculated as L’/y’ (supported) […]
