概要

• 論文の詳細を見る

• Based on its effect on the normal modes of a structure, a method for damage detection is proposed. The method uses frequency measurements before and after damage to locate the damage and estimate its severity in shear buildings. Numerical simulation is performed of a 10-story shear building, with different cases including complete eigenfrequency measurements, incomplete frequency measurements, and differing measurement noise levels. The method is further evaluated by vibration tests of two frame models. Numerical simulation and experimental verification clearly show that, for shear buildings, damage severity and locations can be accurately inferred using the present method.
