An investigation on vulnerability assessment of steel structures with thin steel shear wall through development of fragility curves

Fragility curves play an important role in damage assessment of buildings. Probability of damage induction to the structure against seismic events can be investigated upon generation of afore mentioned curves. In current research 360 time history analyses have been carried out on structures of 3, 10...
