Abstract
In this paper the linear dynamic response of the high-rise and massive building of the Ministry of
Agriculture of Iran, shaken by the Manjil earthquake (20th June 1990), is studied. The building is
situated in Tehran & has twenty seven stories. Its system is composed of shear walls that carry the
vertical loads as well , and the floors are built of concrete slabs together with some seperating walls of
light wood or plaster. This building is one of the few engineering buildings in Iran that is equipped with
Strong Motion Accelerographs of SMA1. The destructive earthquake of Manjil triggered the instruments of the
12th and 22nd floors, plus a few of other instruments of Tehran free - field area. The data of the building
is fed into the ETABS (Extended Three-dimensional Analysis of Building Systems, version 5.10) software, and
with the use of Modal Superposition Method programme, the recorded and computed motions are compared with
each other. The results show that the linear elastic model is appropriate for dynamic behavior of the
high-rise buildings, and the ETABS software is comprehensive for such investigations.
