Ground motions from the near- field contain distinct pulses in acceleration, velocity, and displacement histories, which can generate higher base shears and drifts, than signals from the far-field. Besides, under those inputs, the ductility demand could be increased. In a first step, the worst seismic scenario in the highest seismic area of the Iberian Peninsula under the premises of near-field loading is defined. The obtained seismic inputs are directly related to the structural properties of singular masonry vaults, which are representative of precious local constructions. In a second step, the sensitivity analysis, focused on the material properties, is carried out by means of non- linear transient analysis. A constitutive law for brittle materials able to capture collapse mechanism under dynamic loading via FEM is implemented. From those analyses, the influence of different control parameters on the structural response is identified, and deviations on the seismic response are analysed in terms of collapse mechanisms.
