Abstract:
objectives of the committee were to assess a degree of damage to be caused in reinforced concrete (hereafter refers to as RC) structures under severe earthquakes, to provide seismically safe and economical structures by means of appropriate repair and retrofit, and to establish such a seismic design method. For achieving these purposes, the committee collected and reviewed the previous works on the following items: (1) framework of the seismic design method toward better consideration of restorability, (2) current guidelines or standards relevant to the damage evaluation and control, and their applications to actually damaged structures, and (3) practical art-of-the-engineering related to the performance evaluation method of repaired and/or retrofitted structures.
