3 Σύντομη παρουσίαση της επιστημονικής εργασίας που παρουσιάστηκε στο συνέδριο ABSTRACT A modified procedure is presented for estimating frequencies and the peak values of base resultant forces of eccentric irregular buildings due to earthquake ground motions characterized by response spectra. This procedure retains the simplicity of the methodology presented by the first of the authors in earlier papers, but it presents higher accuracy in multi-story buildings composed by very dissimilar types of bents, which are usually defined as irregular structures. As a result, the first mode center of rigidity (m -CR) is determined with superior accuracy and this allows the practicing engineer to form a structural configuration which will sustain minimum rotational response, simply by allocating the resisting elements in such a way that this point lies close to the axis passing through the centers of the floor masses. It is demonstrated in the companion paper, that inelastic asymmetric building systems with a similar structural arrangement are also very effective during an earthquake, since they present an almost translational response. The accuracy of the proposed modified procedure is illustrated in mixed-bent-type eight-story structures, which are characterized by Eurocode (EC8-2004) as irregular structures, and comparisons are made with the accurate results obtained by response spectrum analyses using the SAP2000 computer program.
