Human-Induced Vibration on Light-Gauge Steel Lightweight Concrete Composite Floors
Light-gauge steel lightweight concrete composite floors have several attractive properties and are increasingly used for construction. However, under human walking activity, these floor systems are vulnerable to excessive and complicated vibration, resulting in discomfort and complaints from people. A finite-element numerical study has been performed to investigate the vibration of light-gauge steel lightweight concrete composite floors. Two methods have been adopted in this study. The first method uses time-domain analysis to predict the peak acceleration response under the human walking excitation represented by the Fourier series loading function. The second method is a simplified frequency domain analysis that can predict the steady-state response to walking using the acceleration frequency response function with a reduction considering the incomplete resonant build-up. Various light-gauge composite floor structural models have been considered taking into account two types of concrete, lightweight and normal weight, and floor beam span ranging from 5 to 8 m. Results show that human walking activity could induce the light-gauge steel lightweight concrete composite floors to reach inappropriate levels of vibration when used in the quiet areas, and resulting in a violation of the human comfort criteria for these types of structures.
