Implementation of performance in concrete design code

초록

Performance-based design is an upcoming issue in the design codes for civil structures. Many international design codes introduced in recent years acknowledge the performance concept and open their doors to it. Even if the idea of performance seems to be easily understood by civil engineers, however, it is not easy to figure out how such an idea can be melted down in the codes practically. The paper presents a conceptual way of implementing the performance-based design into a design code in a systematic manner. The paper limits its focus on the safety and serviceability for a design. Basically, the reliability index combined with the probability of failure can be utilized as the reference value in defining the level or quality of a design. The design working life depending on the importance of a structure is also inter-related as a guideline in leveling the required quality of a civil structure.
