The dynamic analysis of a building structure - acoustic volume interaction system excited by human footfall impacts

Record type: Conference or Workshop Item (Other)

A numerical model is developed using a mixed finite element method to simulate building structure – acoustic volume interaction systems excited by human walking impacts. The pressure in the air volume and the displacement in the structure are chosen as fundamental variables to describe structure – air interaction dynamics. The governing equations and corresponding variational formulation are presented. Based on available experimental results on the footfall load history, an approximate load function is proposed to simulate the measured dynamic footfall load as a moving load with a walking speed and dynamically applied to each foot contact point. A simple example is presented to illustrate the method which reveals the mechanism of low-frequency vibration produced by human walking impacts using an air-structure interaction method. The benefits of the proposed method are summarized to provide a guideline using the method to practical house designs.
