The economic impact of seismic retrofit on heritage reinforced concrete buildings

Maria Boştenaru Dan

Rezumat/Abstract. Groups of actors (architects, engineers, inhabitants, investors) put different priorities in interventions on heritage buildings. Seismic retrofit can be done at different levels, from avoiding collapse up to assuring immediate postearthquake functionality. The costs of the retrofit and repair differ depending on the targeted performance between these two poles. Not only an earthquake has impact on a heritage building, but also the retrofit measure. A solution must be found on how much change we accept for retrofit and how much repairable damage we take into account. A developed system counted building elements according to their degree of damage from numerical simulation. Device computations for the retrofit and the repair measures were done considering the material prices and the labor hour prices. Diagrams/tables have been built to see how the total costs vary as addition between the preventive retrofit and the postearthquake repair, compared to costs of rebuilding.
