Abstract

Multisegment SMART traversing beams with built-in sensing and actuation capabilities have been considered in various critical applications where weight and deflection are of utmost importance, such as in long support bridges. With such capabilities, light weight SMART segments can be added one at a time to extend the traversing beam over long gaps with minimal deflections and stresses. Each segment of the SMART beam has a set of distributed wire sensors, embedded in its bottom fibers, to sense the beam deflection and another set of wire actuators, embedded in the top fibers, to compensate for the encountered deflections. The theory governing the operation of this class of SMART beams is developed and validated experimentally on a two-segment prototype of the traversing beam whose sides are made of a photoelastic material.
