The AISC 341-16 and AISC 358-16 Edition changes have been implemented into RISA-3D v19.
To select this code for your design, simply choose the AISC 360-16 code from the Codes tab within the Model Settings. Previously, when the AISC 360-16 code was selected, the seismic detailing checks still used the AISC 341/385-10 codes.
A few notable changes in RISA between AISC 341/358-10 and AISC 341/358-16 include:
Calculation of limiting width-to-thickness ratios in Table D1.1
Calculation for bracing requirements for moderate ductility members or high ductility members
Calculation of sum of expected flexural strength of beams at the plastic hinge location for special moment frames
Calculation of required shear strength of connections.
Calculation of expected compressive strength for braced frames.
Use of ASTM A1085/A1085M for HSS shapes
