FRAGILITY CURVES FOR WOODEN HOUSES CONSIDERING AGED DETERIORATION OF THE EARTHQUAKE RESISTANCE
In 1995 Hyogo-ken Nanbu Earthquake, there is a sharp contrast between the damage ratio of new wooden houses and aged wooden houses. Saratani et al. said that it is caused that buildings earthquake resistance is associated with a performance decrement of deformation by aged deterioration. We built fragility curves for wooden houses considering aged deterioration of the earthquake resistance based on ratio of damage of buildings in 1995 Hyogo-ken Nanbu Earthquake and its strong motion distribution. We set the parameters (index of strong motion) for fragility curves as below. Choose 4 periodical band, 0.5-2.0 sec, 0.5-3.0 sec, 1.0-2.0 sec, and 1.0-3.0 sec. Calculate Peak ground velocity, Maximum velocity response, and Average velocity response for each periodical band. As a result of parametric study, we have best correlation coefficient by the case choosing 1.0-3.0 sec periodical band and Average velocity response.
