ABSTRACT
Japan Society of Seismic Isolation (JSSI), a key organization for promotion and codification for the
base-isolation scheme in Japan, has decided to initiate a new activity regarding passive control
scheme. The JSSI Response Control Committee is currently formulating the Manual for Design
and Construction of Passively-Controlled Buildings. This paper, together with the companion
paper (Ref. 15), describes such an effort of the committee. In particular, Part 1 addresses
background and scopes of the manual as well as design methods.
INTRODUCTION
Passive control scheme has established its status as a viable means to enhance seismic performance
of buildings [1-14]. Social desire for adopting this scheme as well as base isolation scheme has
increased "considerably after the 1995 Kobe earthquake. Up to the year 2002, the number of
passively controlled buildings has increased to about three hundred in Japan. For the sake of
further growth in this technology, it is necessary to promote understanding of the passive control
schemes, as well as to create a uniform basis for assessment of the various stages to be followed
during the design and construction process.
Pursuant to this need, the Japan Society of Seismic Isolation (JSSI), a key organization for
promotion and codification for the base-isolation scheme in Japan, has decided to initiate a new
activity regarding passive control scheme: the JSSI Response Control Committee is currently
formulating the Manual for Design and Construction of Passively-Controlled Buildings [3-14].
The manual will refer to the mechanism, design, fabrication, testing, quality control, and analytical
modeling of various types of passive control devices, as well as design, construction, and analysis
of passively controlled buildings.
The manual is being developed by researchers, designers, and more than twenty device
manufacturing companies. This paper, together with a companion paper (Ref. 15) describes such
an effort. In particular, this paper will address background and scope of the manual, as well as
design and analysis. Details will be explained in the other papers (Ref. 16-27) that are also to be
presented in the present and following sessions in this congress.
