A SIMPLE DAMAGE ESTIMATION METHOD FOR RC LOW-TO-MEDIUM-RISE BUILDINGS USING NEXT-GENERATION HOUSEHOLD GAS METER CONSIDERING THE EFFECT OF BI-DIRECTIONAL INPUT

Structural health monitoring has been attracting attention because of the need to quickly determine the degree of building damage immediately after an earthquake. In a previous study, a simple damage assessment method for RC buildings assuming the installation of next-generation gas meters was proposed using the change rate of the natural period when the velocity response spectrum reaches its maximum value. In this study, a shear model was analyzed using only unidirectional input ground. In this paper, the applicability of the damage assessment method is investigated using a frame model considering under two directions of ground motion.
