Abstract
While the seismic design codes for reinforced concrete structures were revised in several organizations after Hyogo-ken Nanbu earthquake, many research works are even now continued to improve the accuracy of evaluating deformation capacity. On the other hand, the studies to introduce performance-based design into a seismic design are set on foot. In performance-based design, providing required performances of structures, we check whether performances may satisfy dynamic responses.
In this paper, to aim at a seismic design method based on the performance-based design for reinforced concrete members, deformation limit points related to damage levels taking restorability into account are defined and a method of evaluating the deformation capacity of each limit point is proposed.
