Seismic risk analysis of multistory reinforced concrete structures in Saudi Arabia
(چکیده مقاله) :
Abstract :
In this research, analytical fragility curves for typical mid-rise plane reinforced concrete
moment-resisting frames in Kingdom of Saudi Arabia, KSA, which is considered low-
seismicity area, are presented. The fragility curves are developed for 12-story reinforced
concrete structure designed according to Saudi Building Code under dead, live and seismic
loads. Three cities with different seismic intensities; Abha, Jazan and Al-Sharaf were
selected to cover various values of mapped spectral accelerations in KSA. The 0.2-second
spectral accelerations range from 0.21 g to 0.66 g while the 1.0-second spectral
accelerations range from 0.061 g to 0.23 g. Incremental Dynamic Analysis, IDA, was
performed under twelve ground motions using SeismoStruct. Five performance levels;
Operational, Immediate Occupancy, Damage Control, Life Safety and Collapse Prevention,
which define different possible damage states of a building after an earthquake, were
considered and monitored in the analysis. Based on the results of the IDA and statistical
analysis, the probability of reaching or exceeding a specific damage state was calculated for
each structural model in the three cities. The results were
fitted and the fragility curves
were developed and presented.
