“…The seismic vulnerability can be reduced with appropriate rehabilitation schemes [2]. Many authors have been publications on the decision analyses for seismic rehabilitation of building structures [3], and [4]. These efforts are oriented on to develop a decision support that takes into account multiple criteria, including loss of building function.…”

This study aims at presenting a methodology for the taking decision about the retrofit or the destruction of the damaged buildings by an earthquake. The proposition is founded on the damages caused by the seism of Boumerdes in Algeria, on 23 May 2003. This work can to help the authorities and owners to make a choice concerning the retrofit or the destruction of buildings and reconstruction.The analysis begins by the identification of the structural damages in the structures, then by the evaluation of costs of the reparations and the retrofit of all functions of the building. If the owner has contracted insurance, the amount of insurance is deducted. After this step, this cost is compared to the cost of the destroying of the old building and the rebuilding cost of a new similar building. The life duration of structure is integrated respectively for the retrofitted building and the build of a new equivalent building. The depreciation of capital according to the time of exploitation is calculated on the reference: fifty years for the new investments, and twenty-five years for the retrofitted buildings.The resolution of the problem uses the comparison between the cost of retrofit divided by twenty-five to which added the amount of insurance, and the cost of new equivalent construction divided by fifty to which added the amount of destruction. This approach gives a result according to retrofit, insurance, the equivalent new building and the depreciation of capital. The compilation of the actualized costs according to each zone permits to have a quick vision about the economical decision. The cost of the urban land component is not taken in account and the network is considered in good state.

“…In general, detailed case-by-case investigation is required for selecting a suitable retrofit method [5,6]. For steel frame structures, improving moment capacity for critical joints and members is usually one of the main tasks in the retrofitted design [7,8].…”

SummaryThe Thiel–Zsutty (TZ) model predicts mean and the probability distribution function for earthquake damageability of building as a function of peak ground acceleration. ATC‐13‐1 provides an alternate damageability model based on modified Mercalli intensity characterization of ground motion and a beta distribution function for selected building types. This paper provides a reconciliation of the TZ and Applied Technology Council (ATC) methods. It is shown that the beta distribution can provide a continuous representation of the step‐wise TZ Markov distribution function. When the TZ model uses a compression factor for the standard deviation to represent the degree of uncertainty in the parameters, then the TZ results are found to be consistent with the ATC‐13‐1 distribution function for a specific compression factor of 0.40. This paper provides a new, simply applicable method to determine the damage distribution function for a given site, building type, and site conditions; using a beta distribution and allowing inclusion of the degree of confidence the assessor has in the determination of the parameters. New equations are provided to estimate the mean, standard deviation, and upper confidence limit of the damage ratio.
