Direct Analysis Method for Steel Design by Yu Pi is a document available to read on EtoBox.
The direct analysis method is used to check the steel structure. Second order effects, including P-Δ and P-δ, are considered. Notional loads of 0.003 times the factored loads are included to account for imperfections. Tau_B is taken as 1.0 to simplify design by automatically reducing member properties to 80%. Nonlinear analysis shows second order amplification is below 1.7, so notional loads only need to be applied to vertical load combinations. Key load combinations are analyzed nonlinearly to check the st
