Seismic assessment of double-storey house is investigated using fragility curve. Fragility curve is employed to determine the percentage Confident Interval for a precast house based on the experimental work. A full-scale of precast house is constructed on strong floor and tested under quasi-static lateral cyclic loading. The seismic performances of two parallel walls are observed during experimental work and classification of their damage states are according to the drift limits. Visual observations on the structural damages are recorded such as width of cracks on the wall-column interface, crack propagations on the column, spalling and crushing of concrete. The damage states limit of these walls panels are according to the definitions and descriptions as given in HAZUS 99-SR2. Colour-coded system is fully utilized in order to identify performance level, damage level, drift damage and ductility factors. Fragility curve is developed based on the probabilistic hazard level, cumulative probability function and classification damage-states. Level Confident Interval safety of double-storey house is assessed based on the plotted fragility curve and experimental work. Prediction damage states of this house at Design Basis Earthquake (DBE) and Maximum Considered Earthquake (MCE) can obtain from fragility curve analysis. © 2013 The Authors.
