In the real case, the structure is loaded with 176 pounds of weight and excited with a PSD spectrum. I&#8217;ve done the spectral analysis (SPER) after the mode extraction and then combined the modes. Then I&#8217;ve done the static analysis. How can I combine the results given by the modal cqc combination and the static analysis to obtain the complessive stress of the structure?
