RISA-3D 9.0 adds extra functionality to the load combination generator. This is available by pressing the LC Generator button when in the Load Combinations spreadsheet.

There are now three tabs that allow for much more flexibility:  Gravity, Wind, and Seismic.

For Gravity load combinations you can now choose whether to include RLL, SL or RL in your load combinations. You also have the option of adding notion load basic load cases.

For Wind load combinations you can now choose whether to include roof wind load and notional load basic load cases.

For Seismic load combinations you can now include PDelta, the vertical portion of seismic loads, bi-directional seismic loads, notional loads and the ability to add overstrength load combinations.
