Plate Elements Available in Material Takeoff

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.

Eurocode Concrete Design According to BS EN 1992-1-1:2004 A1:2014 now…

The BS EN 1992-1-1:2004+A1:2014 has been implemented in RISA-3D version 16.0 and RISAFloor version 12.0. To select this code for your design, simply open the Model Settings and under the Codes tab select BS EN 1992-1-1:2004+A1:2014 for concrete: After running an analysis, the detail reports will display the code that the user has selected for their concrete design above the results:…

Challenges when using Analysis Offsets

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 cases setting the analysis offset to top of member should be used with caution since it can lead to odd and unexpected behavior within the model. While using analysis offsets may make the rendered view of your model look more realistic, your analysis model will get unnecessarily complicated. To start, let’s look at a simply supported beam example and compare the bending moment with and without the analysis offset. Moment diagram with the Analysis Offset set to None: Moment diagram with the Analysis Offset set to Local -y axis (top of member): When comparing the results, it appears that we have a fixed-fixed beam rather than a pin-pin beam. What is happening can be shown by modeling this situation as RISA does internally, adding rigid links and dropping the member down by half its depth (11.95”). The rigid link members are modeled with fixed-fixed end…
