Statue's 'Heartbeat' Sends Messages on Structural Corrosion: Sensors Ensure the Golden Boy Stands Tall

摘要

The Golden Boy's "heartbeat" is actually a vibrational reading taken from sensors located inside the hollow, cast-bronze statue and is part of an overall structural health-monitoring (SHM) system that continuously sends data to the ISIS Canada SHM Lab on the structural integrity of the statue. The Golden Boy has a natural vibration frequency of 3 Hz, or three beats per second, according to Aftab Mufti, professor of Civil Engineering at the University of Manitoba (Winnipeg, Manitoba, Canada); program leader and president of ISIS Canada; and first president of ISHMII (International Society for SHM of Intelligent Infrastructures).
