Our faculty member, Assoc. Prof. Zeynep Tuna Değer, along with her co-author, has published work on representing energy degradation in reinforced concrete (RC) shear walls under cyclic loading at the 3rd International Workshop on Energy-Based Seismic Engineering (IWEBSE 2025) in Istanbul, Turkey.

The study focuses on how energy factors can be used in structural analysis software to capture reductions in energy dissipation per cycle. While modern software like CSI ETABS allows for nonlinear modeling and energy dissipation, guidance on the appropriate values of these factors is limited, and current earthquake codes do not provide recommendations. As a result, energy degradation—a key aspect of seismic performance—is often neglected in practical engineering applications.

This study aims to determine the energy factors to be used in common analysis software to represent energy degradation in RC shear walls under cyclic behavior, improving the accuracy of seismic performance predictions and supporting engineers in more realistic structural analyses.
