Utilization of Residual Displacements in the Post-Earthquake Assessment

Abstract eng:
A new post-earthquake seismic performance assessment method which takes into account residual displacements attained by the damaged structures is presented. The post-earthquake residualwhich takes into account residual A new post-earthquake seismic performance assessment method for structures displacements and the visual indisplacements is proposed. The post-earthquake residual displacements and the observable damage to the spection of the damage to the structure are considered to obtain improved estimates of the maximum deformations structure are considered to obtain improved estimates of the maximum deformations that took to yield a better experienced by the structure. The improved estimates of the maximum deformations are expectedplace during the earthquake. The improved estimates of the maximum deformations are decisions regarding the post-earthquake picture of the extent of damage to the structure. As a result, better informed expected to yield a better picture of the extent of damage to the structure. As a result, better the uncertainties associated with the structural propusability and repairability of the structure can be made. Bothinformed decisions regarding the post-earthquake usability the probable errors due to the imperfectness of Both the uncertainties associated with the proposed erties andand repairability of the structure can be taken. the analytical models are considered in the structural properties trial the probable the method to the imperfectness of the analytical models are considered in the method.

A trial application of the method to a real structure tested on a shaking table is presented.
