In models with tension-only members (or compression-only members), the Amplified first-order elastic analysis method should not be considered in the Design settings for Steel AISC code design.
The symptoms can include tension-only braces being designed for significant axial compression (and usually failing), braces being designed for no force at all, or other members being designed for forces that are very different from the analysis results.
Do not include this option for Amplified first-order elastic analysis in the Design Settings when the model includes tension-only members.
When second order P-Delta analysis is considered, this option is not available, so the problem cannot affect models using P-Delta.
