HUMAN RESPONSE TO DYNAMIC MOTION OF STRUCTURES

In this paper human reactions to the vibrations of fixed structures are discussed, and magnitudes of motion which should be acceptable to the majority of people, are suggested in tables and diagrams. The values suggested for acceptable horizontal motion magnitudes for bridges are higher than those for buildings since bridges are generally open structures on which there is an interaction between the users and environmental forces that causes the bridges to respond dynamically. Also, in contrast to occupied buildings, bridges are generally used only for short periods at a time by those crossing, skilled work is usually suspended in storm conditions and people are generally not constantly engaged in either working or standing on bridges during storms. The suggested values of acceptable motion magnitudes for bridges does not account for transport functions, which could be interrupted before the limit of acceptability for humans is reached, or for the possibility of structural damage.
