RISA-3D 9.1 Incorporates the AF&PA SDPWS 2008

The new 2008 AF&PA Special Design Provisions for Wind and Seismic has now been implemented for wood wall panel design in RISA-3D.

Because many of these provisions were already implemented in the previous version of RISA-3D, the code selection had been modified to include both the 2005 and 2008 SDPWS. Simply select the AF&PA NDS-05/08: ASD selection from the Wood code selection in Global Parameters and your wood wall panels will be designed to these specifications.

This specification includes the following updates:

  • Updated calculation of the Shear Capacity Adjustment Factor, Co per an equation rather than from a table.
  • Updated calculation of the Sheathing Area Ratio, r.
  • Higher limits on acceptable shear wall sheathing capacities for Perforated Shear Walls.
