This paper briefly reviews the development of seismic design requirements and the construction of highrise reinforced concrete buildings in Japan. The Urban Building Law limited the building height to 100 feet in 1919. The 1963 revision of Building Standard Law removed the height limitation, but the law required that the design and construction of high-rise buildings should be approved by the Minister of Construction because of their importance in the society and also because of the severe damage of high-rise buildings in the 1923 Kanto (Tokyo) Earthquake Disaster. The high-rise building of reinforced concrete was realized in the mid 1970s with the demand for high-quality condominium and apartment buildings in urban areas. Performance-based design regulations were introduced in the 1998 revision of Building Standard Law. A separate notification was issued to define performance requirements for high-rise buildings, but no design calculation methods were specified. This paper presents the state of practices to satisfy the performance-based regulations for gravity loads, snow loads, wind forces and earthquake forces with emphasis on the design of reinforced concrete structures.
