In a previous article we discussed how the Analysis Offsets feature in RISA-3D works and how it can be used to model members at top of steel.  In this article, we will discuss some specific situations and how the results change with the analysis offset set as top of member (local -y axis). In most […]

Have you ever wondered what the Analysis Offset feature does?  Let’s take a look at how this feature can be used to model members at top of steel. The analysis offset feature allows a member to be offset from its centerline for analysis. When it is enabled the member is actually shifted to the offset location for […]

The new AISC 360-16 15th Edition changes have been implemented into RISA-3D v17.0 and RISAFloor v13.0. To select this code for your design, simply choose them from the Codes tab within the Global Model Settings. A few notable changes in RISA between the 14th Edition and 15th Edition of the AISC code include: Updated shape database […]

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 […]
