Basic Description Pattern based skip loading has recently been added into RISAFloor beam design. This can be turned on or off using the checkbox in the Solution tab of the (Global) Model Settings shown below.
The consideration of Live Load reduction is a feature that has been in RISAFloor from the very beginning. However, recent changes to the interface make it significantly easier for you to understand how live load reduction is affecting the design forces in your structure.
RISAFloor v11 allows users to add parapets while allowing the program to calculate the wind loads per the ASCE 7 parapet wind loading requirements.
RISAFloor v11 now includes the option to add parapets and parapet loading to a building.
RISAFloor does not record the applied area loads in a spreadsheet. To simplify modeling, it instead assumes a default area load over the entire diaphragm area. Additionally, you are free to apply area loads beyond the default loads. Whatever is drawn last will be considered the applied loading...
With the new release of RISA-3D v13.0, you now have the ability to include moving load combinations in a Batch solution. Just select which load combinations you want included in the Batch solution using the “Solve” checkboxes in the Load Combinations spreadsheet.
RISA-3D and RISA-2D will allow you to add a moving load pattern to your model and include it in your envelope solution.
RISA-3D and RISA-2D come with a default list of existing moving load patterns. These are listed in the Moving Loads Library which can be viewed by clicking on the Moving Load Patterns button in the Advanced tab.
In RISAFloor, there are several different Load Categories that define Live Load. The IBC and the ASCE7 both have provisions that allow you to reduce the tributary area of the Live Loads. These codes have equations that adjust the Live load based on the tributary area and usage (KLL*AT). In...
