dc.description.abstract |
Existing predictive models of self-centering precast concrete walls with posttensioning are generally computationally expensive. While simplistic models have a low computational cost, they are generally incapable of simulating cyclic behavior of these walls. Hence, a new computational model suitable for characterizing cyclic response of selfcentering precast concrete walls was developed with emphasis on accuracy and computational efficiency. The proposed model consisted of a bed of truss elements at the base of wall where the rocking response is expected, truss elements for the post-tensioning tendons, and an elastic beam-column element for the wall panel. To ensure the accuracy of wall response, including the quantification of residual displacements, a robust concrete hysteresis model was required in the analysis. The proposed modelling technique was verified against five experimental tests completed on self-centering precast concrete walls. In all cases, the model accurately captured the overall cyclic behavior and residual displacements of the self-centering precast concrete wall. Furthermore, the models also satisfactorily captured several local response parameters, including the wall uplift, neutral axis depth, lateral drifts at which concrete spalling and crushing occurred, and post-tensioning force for both loading and unloading cycles at all ranges of lateral drifts. |
