A Review of the Application of Incremental Dynamic Analysis in Isolation Systems

Abstract

The Incremental dynamic analysis(IDA) method is an emerging calculation technique that accurately estimates the failure probability of structures, typically means the collapse rates of structures during the earthquakes. It has been widely utilized in the analyzing and designing processes of various engineering projects, including traditional and seismic isolation structures. This paper systematically reviews the application of IDA in the traditional seismic isolation structure, the special seismic isolation structure and other unique structures. It mainly focuses on the considerations of multiple factors that affect the safety of seismic isolation structures, the reliability of IDA in its structure design process, the guidance that IDA results have provided for the design scheme selection of complex structures, and the utilization of IDA in seismic isolator design. This article offers an overview of applying IDA in such a wide range of structures, proving its practical values in both assessing and designing processes. It also implies some directions for future investigation to increase its accuracy and calculation speed.
