Abstract
A building safety verification system and a building safety verification method for estimating a degree of damage of a building after an earthquake occurs are provided. The building safety verification system includes: an inter-story displacement measurement unit which obtains, from measurement data of acceleration sensors which measure accelerations of a plurality of stories in a building, an inter-story displacement of each of the stories; a natural period measurement unit which obtains a natural period of microtremor of the building from measurement data of a micro vibration sensor which measures micro vibration of a highest story of the building or a story near the highest story; and a building safety evaluation unit which evaluates soundness of the building from the inter-story displacement obtained by the inter-story displacement measurement unit and the natural period obtained by the natural period measurement unit.
