ABSTRACT
Part 2 introduces the manual contents regarding analytical modeling, numerical algorithm, and
example computer codes for load-deformation relationship of each device type. It also explains
another part of the manual referring to the mechanical, chemical, and environmental characteristics
as well as acceptable range and quality of each device type. Manual policies on declaration of
device property, assurance of device quality, and maintenance for long-term use will be explained.
INTRODUCTION
The companion paper (Part 1, see Ref.l) explained background and scopes as well as design
concept of the JSSI Manual for Design and Construction of Passively Controlled Buildings. It
introduced the tasks of the subcommittees and the working groups, and briefly explained the
contents of the manual regarding classifications of the seismic energy dissipation devices and
framing types, as well as comprehensive methods to evaluate effectiveness of the devices and the
framing schemes [1].
The present paper (Part 2) introduces the manual contents regarding analytical modeling, numerical
algorithm, and example computer codes for load-deformation relationship of each device type,
which aims at promoting reliable time-history analysis of the passive control system. The contents
were developed by the researchers and the engineers of software, construction, and design
companies. Part 2 also explains another portion of the manual referring to the mechanical,
chemical, and environmental characteristics as well as acceptable range and quality of each device
type. The contents were created through extensive collaborations among more than twenty device
manufacturers and their close interactions with the structural engineers and the researchers.
Finally, manual policies on declaration of device property, assurance of device quality, and
maintenance for long-term use will be explained.
ANALYSIS MODELS AND DISSEMINATION OF COMPUTER CODES
In Japan, significant progress is being made in numerical modeling of the devices (Fig. 1) for
time-history analysis of passively systems. However, the new models, in spite of enhanced
