Parapet Wind Loading in RISAFloor

You can now model parapets for analysis in RISAFloor and the program will calculate the wind loads per the ASCE 7 parapet wind loading requirements.

How to add a Parapet to your model?

The Floors spreadsheet has a parapet height per floor which is the default for the entire floor level.    You can then go into the Columns and Wall Panels spreadsheets to customize the height of your parapets around the edges of your roof.

For columns, the program will go around the edge of your roof and find the column parapet height at each location.  The smaller of the two values between the two columns is the parapet height.

Once this is complete you can solve your model and use the Director to go to RISA-3D, where you view the Wind Load Generation dialog.

From here you can see the defined geometry and the wind load at each parapet. This load is then lumped in with the regular roof wind load to give a total wind force in each direction.
