The seismic fragility of piloti buildings having straight plans was evaluated varying the location of core. Since piloti buildings are known to exhibit soft-story vulnerability during earthquakes, the influence of core location requires careful consideration. Four types of piloti were modeled according with the different core location within the straight plan. Based on the estimated capacity curves, the performance points were determined using the capacity spectrum method considering as a equivalent damping as well as a bilinear idealization. Subsequently, artificial ground motions compatible with the target design spectrum were employed to develop probabilistic seismic fragility functions. The lognormal fragility models, median capacities and logarithmic standard deviations, were estimated through the maximum likelihood estimation. The results confirm that the location of the core wall is a key factor governing the seismic fragility of straight plan piloti buildings, and minimizing core eccentricity is essential for achieving a stable seismic performance.
