Capacity curve

Post by sanya greek »

Hello!

After the Pushover Analysis (Greek seismic code KANEPE) i have the next Capacity Curve

Image

From Appendix H5 - KANEPE and from KANEPE i know that we mast have approximately equal areas above and below the dotted lines, like in image below

Image

Why do i have different result?

Thank you!!!

Dear sanya greek,

The program tries to cover the requirements 1)for α<=1 and 2)for approximately equal areas. The algorithm fulfils the 1st requirement first and then tries to find the best solution to fulfil the 2nd requirement. Probably, if you try to run further the analysis and have a declining branch in your curve, the algorithm will find a better solution for the second requirement.

If the analysis stops before it is completed then please refer to the "Convergence and Divergence flags" and "Tips to Solve Convergence Problems" topics of SeismoStruct's Help System.
