Abstract
On structures two types of humans may be present. (1) Active humans and (2) passive humans (sitting or standing on the structure). The active humans can excite the structure and cause structural vibrations. The mass of the passive humans will interact with the structure and basically it changes the structural system (modal characteristics and structural vibration levels). The paper addresses this subject and explores the implications of having passive humans present on the structure.
