coordinatescursor

In RISA-3D, RISAFloor, and RISAfoundation the cursor now provides additional information regarding the cursor coordinates. As you move your cursor around on your screen, a box adjacent to your cursor will appear and populate with the coordinates of the cursor. The mouse coordinates that are displayed are the coordinates of the grid point or joint […]

In the RISA-3D when you model a WT brace it exists at the member centroid, which means that no bending ends up in the brace due to the fact that the brace is actually eccentric to the braced frame. In Version 15.0 we added a feature called “Analysis Offset” which moves the centroid of the member […]

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.  Then, you are free to apply area loads over the default.  Whatever is drawn on last will be considered the applied loading unless you are using an Additive area […]

Seismic Forces are generated automatically using seismic parameters R, SD1, and SDS in the Seismic Load Generator when using the Director to go from RISAFloor to RISA-3D or when inserting Seismic Loads on a rigid diaphragm in RISA-3D. And Seismic Load Combinations can be generated using the seismic parameters ρ, Ωo, and SDS and applied […]

RISAFloor column results are available in the results spreadsheets, but you may not be aware that you can also graphically review the input and results of columns. To do this you need to customize your toolbar, which is an option available in the Tools menu: Add the Column Input and Column Result buttons to your […]
