Temperature-Based Model Updating of Bridge Structures
Temperature-based (TB) model updating has been researched as a novel approach to inform numerical models of constructed systems. The overall TB concept utilizes temperature variations as a measureable forcing function for bridges and thus can be used to obtain a complete input-output relationship (or transfer function). This is achieved through instrumentation of both the critical members and movement mechanisms. Studies were conducted on existing bridges where the temperature (input) was measured at select locations along with the corresponding strains, displacements, and rotations (output). Then TB model updating was performed to refine a numerical model according to the measured input-output relationship so it more closely represented the actual behavior of the structural system. This paper discusses the approach for TB model updating along with the primary benefits and drawback of the methodology.
