UTILIZATION OF RESIDUAL DISPLACEMENTS IN THE POST-EARTHQUAKE ASSESSMENT
A new post-earthquake seismic performance assessment method which takes into account residual displacements attained by the damaged structures is presented. The post-earthquake residual displacements and the visual inspection of the damage to the structure are considered to obtain improved estimates of the maximum deformations experienced by the structure. The improved estimates of the maximum deformations are expected to yield a better picture of the extent of damage to the structure. As a result, better informed decisions regarding the post-earthquake usability and repairability of the structure can be made. Both the uncertainties associated with the structural properties and the probable errors due to the imperfectness of the analytical models are considered in the proposed method. A trial application of the method to a real structure tested on a shaking table is presented.
