| Summary: | This study presents the steel fragility curves and performance
curves of industrial buildings of different geometries. The fragility curves
were obtained for different building geometries, and the performance
curves were developed based on lateral load, which is affected by the
geometry of the building. Three records of far-field ground motion were
used for incremental dynamic analysis (IDA), and the design lateral loads
for pushover analysis (POA). All designs were based on British Standard
(BS 5950); however, Eurocode 8 was preferred for seismic consideration
in the analysis because BS 5950 does not specify any seismic provision.
The five levels of performance stated by FEMA-273, namely, operational
phase, immediate occupancy, damage control, life safety, and collapse
prevention (CP) were used as main guidelines for evaluating structural
performance. For POA, Model 2 had highest base shear, followed by
Model 1 and Model 3, even though Model 2 has a smaller structure
compared with Model 3. Meanwhile, the fragility curves showed that the
probability of reaching or exceeding the CP level of Model 2 is the highest,
followed by that of Models 1 and 3. |
