Summary

In Indonesia, most of the multi-story earthquake resistant buildings have been designed with the assistance of the powerful ETABS computer software. Theoretical three-dimensional linearly elastic dynamic analysis is presented in the introductory brief. Backward analysis by the computation of the natural modes and frequencies from the ETABS output are completed in stages to determine manually the modal analysis parameters such as, the modal participation mass ratios, the modal direction factors, the distribution of story forces, base shears and torques. Then to allow self accuracy counter checks of these computer output results, the authors' experiences indicated that for buildings which have multi-towers on large podium masses for most of the mixed-used buildings' analytical models where the lateral torsion is coupled with the translational movements, a few inconsistencies in the computer output were found.
