Recent developments in hybrid structures in Japan--research, design and construction

摘要

A variety of uses for combined reinforced concrete and steel have recentIy been applied in actual construction, which are called hybrid structures. The appearance of the hybrid construction is the result of pursuing the economical, high-efficiency of the construc- tion. This paper first introduces the present situation of design, con- struction and research on hybrid structures, and details of several selected hybrid structural systems are discussed: SRC structures, CFT column systems, RC column S beam system and hybrid wall system. The US--Japan Cooperative Earthquake Research Program on Composite and Hybrid Structures is briefly explained, and finally, research needs are shown.
