To vertify my structure i have used matlab and plottet the eigenvectors. I am trying to compare the results from robot with the results from matlab. is there a smart way to get the eigenvectors ou from robott.. all i seem to get are -0 +0 and 1 -1 ?
I was also wondering if Robot take into acount crackling of the concrete by code reduction factors for shear and flexular deformation when preforming a modal analysis?
No , reduce E or section properties by your own
