Vibration serviceability of staircases is an increasing challenge due to evolving materials and structural forms. To predict the dynamic performance of staircases, accurate models are required. However, few technical guides are available for designing steel staircases, and those that exist are often limited in their applications due to a lack of research. This research aimed to improve the understanding and accuracy of the global vibration response (natural frequencies and mode shapes) predictions of concrete-filled pan tread stairs. In this project, experimental data were collected on two types of staircases and then used to create and tune a finite-element model using shell and beam elements. Using the experimentally updated finite-element model, a parametric study was conducted varying the railing mass and boundary conditions to demonstrate their effects on the staircases' dynamic behavior. AISC design guide procedures were used to assess their applicability for staircases with wall- versus face-stringer boundary conditions. Finally, design suggestions for engineers are provided.
