Target reliability index determination method based on burden risk concept

This paper proposes a decision making method of the target reliability index for structual designers especially code-writers. First, two background concepts of performance based design, i.e., performance agreements and performance specification, is discussed. Conbinating these concepts, this study pointed out the target reliability index can be determined based on both user and designers decision making about their burden risks. This paper proposed a function to compute the target reliability index from the designer's burden risk determination.
