Development of smart systems for building structures

Building Research Institute, Japanese Ministry of Construction, initiated a 5-year research and development project of Smart Materials and Structural Systems in 1998 as a part of U.S.-Japan cooperative research efforts. The U.S. Counterpart is the National Science Foundation. Smart Structural Systems (also called as Autoadaptive Media) are defined as systems that can automatically adjust structural characteristics, in response to the change in external disturbance and environments, toward structural safety and serviceability as well as the extension of structural service life. The research and development of (1) concept and performance evaluation of smart structure system, (2) sensing of structure performance, and (3) development and evaluation of structural elements using smart materials will be conducted.

New RC Design Guidelines for High-Rise Reinforced Concrete Buildings using High-Strength Materials

The increase in the number of high-rise reinforced concrete buildings has accelerated the research on the manufacturing development of high strength materials. Ministry of Construction, Japanese Government, organized a national research project from 1988 to 1993 for the Development of Advanced Reinforced Concrete Buildings using High-Strength Concrete and Reinforcement. This paper introduces the earthquake resistant design guidelines developed as a part of this technical project. The scope is limited to the building height of 200 m, the concrete strength of 60 MPa, and the steel strength of 700 MPa.
