DAFI Calculator

Calculate your post-frame building system load requirements.

The Diaphragm and Frame Interaction calculator helps you design buildings that meet load requirements. You enter the number of bays and default values for stiffness and load requirement, and the program calculates specific values for eave load, horizontal displacement, diaphragm stiffness, shear displacement, and shear load.
