Fragility curves are useful for damage assessment of structures. There are many criteria that affect the reliability
of fragility curves such as transitional damage states, plan irregularity and different measures of seismic
intensity. Determination of fragility of a shear wall structure is important, especially for installations that have
torsional irregularity. In this study fragility curves of a shear wall building with torsional irregularity have been
obtained. This building was subjected to synthetic earthquake motions on the AZALEE shaking table under the
coordination of CEA (Commissariat à l’Energie Atomique) and Electricité de France (EDF) in Saclay, Paris
under the scope of the SMART program.
Maximum inter-story drift values have been used as the damage indicator to obtain the fragility curves and
different seismic intensity measures such as PGA, PGV, PGD and CAV have been used. Thirty bi-directional
horizontal ground motions have been applied for the time history analyses. These synthetic acceleration sets
applied to the structure have different amplitudes in the range of 0.1 to 1 g. Micro modeling approach has been
used to obtain reasonably accurate and consistent results with experiments. ANSYS finite element software has
been used for the response history analyses.
Fragility curves of shear wall building have been calculated according to pre-established damage indicators. The
limits are light, controlled and extended damage indicators. These curves are compared with those of the
HAZUS damage states for correlation.
