A Partial View of Japanese Post-Kobe Seismic Design and Construction Practices

Lessons learned from the 1995 Kobe earthquake have considerably accelerated Japanese research and motivated substantial advances in Japanese seismic design and construction practices. The severity of seismic hazards has been realized, leading to a significant increase in the applications of new technologies to full-scale structures. This paper presents a partial view of post-Kobe design and construction practices adopted in Japan. Described issues include the revision of the Japanese seismic design code, reinforced concrete structures, steel structures, steel-encased reinforced concrete structures, wood structures, and innovative applications of seismic isolation and passive control systems. Recent progress in the diagnosis of seismic resistance and retrofitting of existing buildings is also reported.
