BUILDING SAFETY VERIFICATION SYSTEM AND BUILDING SAFETY VERIFICATION METHOD

Title:

BUILDING SAFETY VERIFICATION SYSTEM AND BUILDING SAFETY VERIFICATION METHOD

Document Type and Number:

WIPO Patent Application WO/2014/109324

Kind Code:

A1

Abstract:

Provided are a building safety verification system and a building safety verification method which are designed to estimate the extent of damage of a building after the occurrence of an earthquake. A building safety verification system is provided with: a relative story displacement measurement unit which, from measurement data by acceleration sensors for measuring the accelerations of a plurality of stories in a building, finds the relative story displacements of the respective stories; a natural period measurement unit which, from measurement data by a microvibration sensor for measuring the microvibration of the highest story of the building or a story near the highest story, finds a natural period of microtremor of the building; and a building safety evaluation unit which, from the relative story displacements found by the relative story displacement measurement unit, and the natural period found by the natural period measurement unit, evaluates the soundness of the building.
