This paper presents the health monitoring for a high-rise steel building based on the vibration measurement. The frequencies, the shapes of modes and the damping ratios are applied to indications of the health monitoring. The time history waves were transformed into the fourier spectra. The frequency for the peak of the fourier spectrum is defined as the natural frequency. The shape of mode is evaluated based on the amplitude of the fourier spectrum for the floors measuring at the same time. The damping ratio is evaluated with the half power method. The natural frequencies and the shapes of modes did not vary at any time, and are suitable for indications of health monitoring.
