What is Performance-based System Reliability Analysis for Steel Moment Frames about?

This study aims to bridge the gap between two major design philosophies in structural design: load and resistance factor design (LRFD) and performance-based design (PBD). While LRFD prioritizes the design of structural members, PBD starts by controlling the system's target parameter. The main area for improvement of LRFD is paying attention to the structure's performance. At the same time, PBD needs to pay attention to the sufficiency of internal members in the presence of local damages. To bring these two attitudes closer together, the study proposes a system-reliability-performance-based design analysis to simultaneously measure the entire structure's safety level associated with the reliability of elements. As a state-of-the-art, new performance-based limit state functions are introduced to measure structural reliability indices corresponding to desired performance levels. Multi-story frames were designed and evaluated based on incremental dynamic analysis. The entire structure was designed and controlled using the linear static analysis method, and static and dynamic nonlinear analyzes were performed to evaluate its behavior. Dynamic analysis of acceleration mapping was also pe
