Experimental Characterization of a Full‐Scale Stair System Detailed to Achieve Seismic Resiliency
Earthquake Engineering &Structural Dynamics, Volume 54, Issue 14, Page 3519-3540, November 2025.ABSTRACT Stair systems are the primary means of egress in and out of a building during and after an earthquake. Therefore, it is essential to detail these critical nonstructural systems such that they remain operable during and after an earthquake of moderate to high levels of intensity.
