Rapid Damage Assessment in Tall Buildings after Seismic Events

Abstract


Rapid damage assessment in tall buildings is essential to confirm safety after seismic events. Structural Health Monitoring (SHM) offers the potential to provide this rapid assessment. However, the initial cost of SHM systems and subsequent maintenance can be prohibitive. This paper proposes a new approach for estimation of interstory drift responses in tall buildings using a limited number of accelerometers. The adequacy of using shear and Euler-Bernoulli beams to model tall buildings is also discussed. A Timoshenko beam model is proposed, and harmful interstory drift and interstory drift angle are defined as a damage sensitive features. A thirty-story building subjected to seismic excitation is considered to demonstrate the efficacy of the proposed framework. These results provide a strong foundation for rapid damage assessment in tall buildings after seismic events.
