    Observing dynamic characteristics (modal frequencies) in nonlinear staged construction analysis SAP

    Hi all, I want to observe how the modal frequencies varies with time ( in a model built with time dependent properties) and each stage. Say for example after 1 year, 5 years, 10 years etc. I used the non linear staged construction analysis for this purpose. But I could only observe the deformed...

    Transient Analysis to obtain Frequency Response Functions (FRFs) of Finite Element Models (FEMs)

    Hi All, I just started my PhD and I want to extract FRFs from FEMs of multi-storey building structures. What are the FE soft-wares would you recommend? What are the books explaining the methodologies. Thank you in advance tharindukatl
