Soil–Structure Interaction Consideration for Base Isolated Structures under Earthquake Excitation
TL;DR: In this article , the authors analytically implemented base isolation with soil-structure interaction (SSI) on a sample structure and developed a very simple solution to add these combined effects into the mass, damping and stiffness matrices of the structure.

Integrating Energy-Based Limit State Functions to Optimize Target Reliability of Bridge Pile for Seismic Events
TL;DR: In this article , a new energy-based limit state function is proposed for bridge substructure systems, including piles, to examine a structure's behavior in the presence of a natural disaster, and the structural target reliability indices for the bridge piles are delineated using the proposed optimization approaches.
