Hartwell hopes to get tie-clip-size sensor packages in the field in 2011, monitoring things like the sag of bridges and wear on machinery.
Those bridges have been sagging of late.
In this model, all sources of geometric non-linearity such as cable sag, force-bending moment interaction in the bridge deck and towers as well as changes in bridge geometry due to large displacements are fully considered.
Since the element is formulated within the framework of large curvature assumption, cables with large sag, as encountered in long-span cable-stayed bridges and suspension bridges, can be modeled accurately.
The application of the derived formulae to sag cables in a real cable-stayed bridge is presented in part II of this paper with extensive parametric studies.
And last year the state was forced to close the Wildcat Creek Bridge, on Interstate 65, for a month, because of sagging and road movement, which some critics called an apt illustration of Pence's neglect of Indiana's construction needs.
Another possibility is that downward cerebellar sag causes stretching and occlusion of the bridging cerebellar veins [ 34].
