Theory of reinforced concrete structure anti-earthquake ductility design

In this paper,earthquake experiences and lessons,expounds the concept of ductility and structure ductility.in important measures. In order to improve the ductility of anti-seismic structure reasonable performance,conceptual earthquake-resistant design and construction measures,the concept of appropriate attention for structure design and structural measures of ductility,plays an important role to ensure the entire building to realize the seismic fortification,"three level" design requirements.
