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 […]

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) […]

RISAFloor Version 10.0.1 has the ability to assign camber design rules which allow the user more control over which members are cambered. A camber is the slight upward curvature of a steel beam which is used to compensate for deflection. A user can assign a camber directly to a member or set up design rules […]
