It is the engineer’s responsibility to ensure that the selection of P-delta, B₁, B₂, fraction of gravity loads for Notional Loads and τ_b used in the stiffness reduction are all consistent and correct. To aid the engineer, a report (see AISC 360 Direct Analysis Validation) is implemented in the Steel Standard Provisions module of RAM Frame that is available when AISC 360-16, AISC 360-10, or AISC 360-05 has been selected as the design code. The report examines the selection of options for P-delta, B₁, B₂, Notional Loads, Reduced Stiffness and τ_b, along with analysis results, and reports on the validity of each criteria selection. If the analysis is deemed invalid, it is the responsibility of the engineer to make the necessary corrections to those criteria selections, or in some cases to modify the structure so that limitations are satisfied.
