Capacity Curve Estimation for High-Rise Buildings Using Limited Number of Sensors. Issue 8 (3rd July 2021) - Pan, Haoran
ABSTRACT: Capacity curve estimated from seismic floor accelerations can provide an informative description of the structural behavior soon after an earthquake. Detailed information on instrumented buildings is not always available. Therefore, this paper proposes a strategy based on the piece-wise cubic polynomial interpolation procedure to estimate the capacity curve for high-rise buildings from accelerations using limited sensors placed at regular intervals along the height of the building. The validity of the method is assessed by numerical simulations and shaking table tests.
