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.
RISAFloor v11 now includes the ability to create custom column strip widths in order to optimize the design of slab reinforcement.
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.
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...
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. Additionally, Seismic Load Combinations can be generated using...
In RISAFoundation v8, you can add a shear splice between slabs so that it acts like a hinge. This is useful for modeling the effects of shear keys or dowel joints between slabs.
In a model that contains both RISAFloor and RISA-3D data it is possible to define your diaphragms as either flexible or rigid for lateral design. You can do this from the Diaphragms spreadsheet in either program:
