Eigenvalue analysis of masonry infilled frame
Posted: 09 Mar 2018, 15:29
Dear SeismoSoft team,
I have modeled a three story reinforced concrete building with masonry infill using the infill element available in the SeismoStruct. When I run eigenvalue analysis, how does the program define the stiffness matrix of the infilled frame ? (By this I mean how does the program know which strut is in compression and which one is in tension for the activation or deactivation of shear springs ? Does that mean the stiffness of all the struts is taken resulting in very smaller value of time period of the building due to very high stiffness ?).
Thank you.
