ABSTRACT

The frequent seismic activities in the UAE along with the adoption of new design provisions necessitates calibrating the seismic design performance factors, namely the reserve strength, response modification and deflection amplification factors, of various structures in this region. This paper briefly discusses sample results from a comprehensive study carried out to verify response factors used in the seismic design of Reinforced Concrete (RC) multi-story buildings in the UAE. For the sake of brevity, the structural design and the adopted approach to develop simulation models for five reference buildings, varying in heights from 20 to 60 stories, using multi-degrees of freedom fiber-based modeling technique is not covered. A large number of inelastic pushover and dynamic collapse analyses are carried out under the effect of twenty earthquake records representing two seismic scenarios and the results are processed to estimate the seismic design factors. The paper presents a systematic seismic vulnerability study and provides practical conclusions that apply to a wide range of multi-story buildings in the UAE.
