STUDY ON REPAIR COST OF DAMAGED EARTHQUAKE RESISTANT CONCRETE WALL BASED ON INTEGRATED ESTIMATES AND QUESTIONNAIRE SURVEY

A preservation of a property of the building structure is important as with its safety. Based on this perspective, the studies on performance-based design incorporating economic indexes have been carried out both in the US and Japan, but the evidences of the repair costs are rarely opened. The authors carried out both integrated estimates and hearing survey of repair costs of a damaged earthquake resistant concrete wall. The estimates of the repair costs are compared with those of the data base opened in US. Finally, the repair costs corresponding to damage levels used in Japanese standards are presented.
