520			_aFragility curve is a powerful tool in performance-based analysis to assess the seismic risk of the structural system. Many parameters like transitional damage states, plan asymmetry and different measures of seismic intensity and damage measures influence the fragility curves. It is essential to establish fragility diagrams for shear wall system where torsion is exhibited. In the present paper, the fragility diagrams of torsion imbalanced steel-concrete composite shear walls (CMSWs) building is developed. In current work, trapezoidal plan building frame- CMSWs structure is simulated to one fourth extents to substantiate analytical findings of modal and corner point’s characteristics with AZALEE shake table results of SMART 2008 project. Incremental Dynamic Analysis is conducted using a suite of fourteen real bi- directional orthogonal horizontal ground motion records. Further, fragility curves of composite shear wall building are compared using pre-defined damage thresholds of SMART 2008 project and HAZUS 2003 technical manual. Damage states of SMART 2008 have been derived for torsion induced Nuclear Power Plant building situated in France. While HAZUS defined limit states for common reinforced concrete buildings with shear walls situated in the United States. The damage states for asymmetric plan building with CMSWs are not prescribed by any seismic code. Hence, damage indices are established in the context of naturally generated incremental dynamic curves for the structural model to obtain more realistic results.
