Reactions are different between Matlab and OpenSees

[xiaosima]

Help me, I have developed two dimensional 9-story nonlinear SAC benchmark steel frame building designed for the SAC project for the Los Angeles in OpenSees. The benchmark structure is 45.53 mx45.73 m in plan, and 37.19 m in elevation.

But the seismic analysis results were different with the results using Matlab.

Who has this model with opensees code, please send to me,help me get out of this mire, thank you very much. My email is 1498399601@qq.com and czq199212@163.com.

Thanks

Are all other results for more basic analyses, e.g., static, eigenvalue, the same or did you create nonlinear response analysis and hope for the best? Take a look at these steps: https://wp.me/pbejzW-1C
