Efectos de la Interacción Humano-Estructura pasiva en propiedades dinámicas de estructuras

This paper investigates the passive effects of human-structure interaction (HSI) on the dynamic properties of civil structures. Experimental campaigns were conducted on a cantilever test structure, first with human subjects standing passively on the structure, and then with inert loads simulating the mass of the occupants. The results show that the presence of passive occupants significantly reduces the natural frequencies and increases the damping coefficients of the coupled human-structure system compared to the empty structure and the structure with imposed masses. This highlights the importance of properly considering the dynamic coupling between people and the structures they occupy, rather than simply treating occupants as additional imposed masses. Anthropometric characteristics of the test subjects, such as weight and height, were found to influence the magnitude of HSI effects, although no direct correlation was observed, indicating that other factors, such as body mass distribution and joint stiffness, also play a role. The pressure insoles data provided more information on how passive occupants interact with the structure in terms of load distribution and dynamic response. These results underscore the need to better understand and model passive HSI to achieve structured designs.
