Estimation Method of Residual Capacity of Moderately Damage Buildings for Efficient and Economical Retrofitting

Abstract

One of the biggest problems encountered after earthquakes is to determine the extent to which the buildings, which are determined as moderate damaged during the damage detection process due to the damage they have seen due to the earthquake, restrict their use in the future, and to predict whether these buildings can be retrofitted within the economic limits. In order to determine the feasibility of the strengthening process, it is necessary to examine the level of damage experienced by the building in the earthquake, the mechanical characteristics of the load transport system elements and the carrier system characteristics and system irregularities. During the observational damage detection process after the earthquake, it is almost impossible to determine how weak or sufficient system elements of the investigated building are. In addition, damage detection processes examine how much damage to the building under investigation in the earthquake. It is not possible to determine the extent to which the building can withstand the future earthquakes. In this study, for the first time in the literature, a method is developed to determine whether buildings defined as moderately damaged are technically suitable for retrofitting and whether the retrofitting process is feasible for technically suitable for these buildings.
