ABSTRACT
In this paper, an optimization procedure of design based on performance is presented. The
performance-based design should consider two types of target performance levels: "generality" and
"individuality". The latter is put sufficiently emphases upon to satisfy clients' demands for
earthquake-resistant performances of structures in large earthquake.
In order to satisfy "individual" performance levels, the investigation includes steps as followed: 1)
determine target performance levels based on clients 1 various and particular demands, by means of
Fuzzy Set Theory, 2) develop detailed criteria for the performance-based design of specific structure
types and performance levels. The framework is demonstrated with a simple example involving a
six-story RC frame.
INTRODUCTION
In recent years, the performance-based design of earthquake-resistant structures is emphasized and
popularized. Based on the code for seismic design, the structural performance in inelastic range is paid
greater attention to satisfied economic and social, and even clients' demands for structures in the large
earthquake. Performance-based design results from and extends the traditional earthquake-resistant
design, which inherits characteristics of traditional design and has some characteristics that the
traditional design have not.
To emphasize the structural performance in inelastic range is to satisfy clients* particular demands for a
structure. It is important that the performance design criteria, which engineers determine, must be hi
agreement with economic and social, as well as clients' demands for a structure subjected to large
