520 _aAn innovative method for detecting seismic damage in a hospital building is introduced in this research, which employs low-cost accelerometers installed on a limited number of floors. In consideration of the concept of mode of vibration, the procedure was founded on modal decomposition, which states that any complex response of the structure can be expressed as the sum of its modal responses.Low-cost accelerometers were fitted on a limited number of floors. Human excitation of the hospital building was performed in order to determine the dynamic properties of the building such as frequency, 3D mode shape and damping ratio.These identified dynamic properties of the building were used as a foundation to prepare an updated numerical model in computer software which closely represented the actual building.The modal decomposition was performed utilizing the "Least Square Error" method, in which the modal acceleration was calculated by minimizing the square of the error between the measured and estimated acceleration responses coming from seismic activity coming from low-cost accelerometers. The sum of these products of modal accelerations with the structure's mode shape produced the estimated acceleration of each floor. Utilizing the obtained modal acceleration, acceleration, displacement, and interstory drift-related hospital building damages were identified.Modal pushover analysis was conducted on updated numerical model for each considered mode to determine the global as well as component level response of the structure. All the estimated results were validated with the actual measurement showing that the entire process studied in this thesis yields a rapid, reliable, and cost-effective structural health monitoring system.
