A vital component of the performance-based earthquake engineering (PBEE) is the so-called fragility function. In this post, I will discuss one method to calculate the fragility function using incremental dynamic analysis. A simplified single degree-of-freedom (SDOF) system is analysed in OpenSeesPy to illustrate the steps in determining the fragility function.

In this post, I provide a brief overview of importance sampling, a sampling-based method widely used in structural reliability analysis. This classical technique has recently drawn my attention because it is frequently cited in the literature I am currently exploring. Revisiting its underlying concepts offers a valuable opportunity to refresh my understanding of this well-established method, which I was first introduced to during my graduate studies.

As part of my personal goal to improve my writing skills, I will be posting several notes (or documentation) I use in learning some tools or concepts I utilize in my current research. These topics will be mostly about structural reliability, optimization and disaster risk. Along the way, I will be able to deepen my understanding on the fundamental principles and at the same time practice to articulate ideas in a clear and concise manner.

Excited to share that I’ve started my postdoctoral research at the University of Sao Paulo (USP)! 🎉
