摘要
The present disclosure is drawn to methods and systems for determining a seismic response of a man-made structure to a given input earthquake. Sensors are used to obtain vibration data for data collection locations from one or more floors of the man-made structure, which may be ambient vibration data or vibration data resulting from forced vibration or shock testing. The vibration data is used to determine modal characteristics for the man-made structure, including mode shapes, natural frequencies, and damping ratios. The mass, centre-of-mass, and moment of inertia is also determined for the floors of the man-made structure. The modal characteristics are then translated from the data collection locations to the centre-of-mass based on the structure of the floors. Then, a seismic response of the man-made structure to an input earthquake is determined using the translated modal characteristics and the mass and moment of inertia of the floors.
