Kinetic Bridges

Report No: 81-R6

Published in 1980

About the report:

This report on kinetic bridges is essentially a state-of-the-art study on two types of bridges whose location or physical characteristics are designed to be time dependent. The first type, called a "relocatable bridge", is essentially for use as a temporary structure that must be erected quickly. Many recent examples of this type are described, ranging from the familiar Bailey Bridge now in common civilian use, to the high technology Armored Vehicle Launch Bridge being developed for military use. The second type, called an "actively controlled bridge", is a newly emerging type of structure whose strength and load-induced deformations can be controlled automatically through a system of sensors, analyzers, and energizers. This report summarizes recent developments of this bridge type and suggests directions where application may be desirable on future bridges, particularly long-span ones.
