Sensored Elastomeric Bridge Bearing and its Application

Abstract

A prototype of sensored bridge bearing was developed, fabricated, tested and planned to be applied in two bridge structures for sensing and monitoring of construction process and service condition. Besides, numerical modeling of the prototype was performed using the finite element method with ABAQUS, and meanwhile the testing results were calibrated. Numerical simulation results of the selected two bridge structures show that certain bearing reactions are sensitive to the interested behaviors and performances. This kind of sensored bearing is considered feasible for monitoring construction, damage scenario, and applied loads.

Implementation of a Load Sensitizing Bridge Spherical Bearing Based on Low-Coherent Fiber-Optic Sensors Combined with Neural Network Algorithms

“…Caussignac et al [ 4 , 5 ] introduced a fiber-optic sensor technique to overcome interference in order to implement measurement in harsher engineering situations. Based on these studies, Y. Zhuang et al related the performance of the bearing to the structural response of the bridge by finite element simulation [ 6 ]. All the studies introduced above are based on elastomer bearing under lower load conditions, because of its simple structure and fairly linear mechanical property.…”
