The requirement to perform a second-order analysis is satisfied by performing a first-order analysis and calculating and applying δb and δs factors to the design forces as outlined in Section 4.4.2 of the Specification. Those factors need to be calculated for each load combination. They are applied to the member forces as indicated in the following equations:
| M* = max(δb, δs)M*m | Eq. (C2-1a) |
where
| δb and δs | = | as defined in the following |
|
M*m
| = | the forces produced from the analysis (considers gravity and lateral forces applied simultaneously) |
