WebUniversity of Canterbury WebThe average deflection at the story height (or diaphragm location) is used to calculate the P-Delta shears for the top and bottom of the story. These shears are then distributed over the width of the wall at those locations. Note P-Delta effect is NOT considered for wall panels if Geometric Nonlinear Stiffness Method is selected.
