Experimental study on vibration serviceability of steel-concrete composite floor
Liang Cao , Jiepeng Liu , Y. Frank Chen
Abstract
In this study, on-site testing was carried out to investigate the vibration serviceability of a composite steel-bar truss slab with steel girder system. Impulse excitations (heel-drop and jumping) and steady-state motion (walking and running) were performed to capture the primary vibration parameters (natural frequency and damping ratio) and distribution of peak acceleration. The composite floor possesses low frequency (
