Hello, I am conducting a study related to my master's thesis in Idecad 6.0053. There are 3-storey framed structure and 3-storey framed structure , which have the same architecture and have the same ground, earthquake and material characteristics. There is a contradiction in performance analysis. The performance of the curtained and framed structure is lower (even very low). (Is this a problem related to the definition of brittle materials?) Related .ide files and the ones I can think of are attached as .pdf. Thank you in advance for your help. I would appreciate if you show alternative documents, links, and helpful resources about IdeCAD performance analysis and pushover feature that is not available in 6.0055.
