In this paper, the dynamic response of a very complex structure which has U
-shaped floors and specially shaped slant columns is described. Shaking tab
le tests of a scale model of the building were carried out to verify the sa
fety of the structure and to confirm the results of a finite element analys
is of the building. The elastic finite element analysis was done with the h
elp of Super-SAP 93, a well-known structural analysis program. From the sha
king table test and the finite element analysis, the dynamic characteristic
s of the building and its maximum responses were evaluated. In the elastic
region, the analytical results were in good agreement with the test results
. At the end of this paper, some suggestions are given for engineering desi
gn of this type of structures.
