Seismic Fragility Analysis of Buildings Based on Double-Parameter Damage Models considering Soil-Structure Interaction

Table 7

Parameters of the fragility functions in terms of PGA-MIDR for the analysed structure with and without SSI effect.

RC buildings	Median PGA (g)				Dispersion

Fixed base	0.29	0.46	1.03	3.69	0.85	0.88	0.88	0.92
SSI model	0.05	0.09	0.26	1.38	0.79	0.82	0.82	0.86
